None!

"I've long held a fascination with unseen spaces, and when I first heard about the vast number of lost rivers in London, it really piqued my interest," says Your Shot contributor Mike Deere, whose photo was selected for the Daily Dozen. "While researching, I came across a very small subculture with similar interests to my own, a small band of curious individuals excited to see the hidden depths that exist so close to our everyday lives but remain all but forgotten."

Deere captured this photo at the junction between the River Westbourne, which was assimilated into the London sewer network during its construction in the 19th century, and the Ranelagh Storm Relief Sewer.

"With lighting options very limited in the narrow, pitch-black tunnels, I opted for backlighting to highlight the shape of the space and the texture of the Victorian brickwork," Deere says.

"I was standing at the top of Guatemala's Acatenango Volcano watching the stars and the city lights from almost 4,000 meters above sea level," says Your Shot contributor Diego Fabriccio Diaz Palomo, a native of Guatemala who climbs the volcano every year. "That was when the Fuego Volcano literally exploded. I start running with a friend for probably half a mile to get to the right spot to shoot the lava. I almost fell down the cliff because I had to be in a really complicated spot to get the right composition."

Diaz Palomo took two long-exposure photos at 90 seconds each. At second 87 of the second shot, lightning appeared in a far cloud on the horizon. "I was without words," he says. "It was indescribable."

Diaz Palomo's picture was published in the recent Moment assignment on Your Shot.

In case you hadn’t noticed, Arsène Wenger manages his 1,000th match for the club. A fair number of tributes have been printed, committed to film or the airwaves. It would be easy to pick the matches which won titles or cups, those you will find elsewhere. It hasn’t been easy to crop it down to five from those nine hundred odd either. I did wonder about pivotal matches and during his time, there have been some crucial games with adverse results driving positive outcomes but frankly today didn’t strike me as one to watch five defeats!

Amid the deluge of tributes of which some of good and some are well-intentioned, Jeremy Wilson has an excellent piece this morning on Peter Hill-Wood.

Blackburn Rovers, April 1998 at Ewood Park

The defeat at Christmas in the reverse fixture was the last Arsenal would suffer that season in the Premier League until after they had been crowned champions. The opening salvo in this match was possibly as good as any Wenger team has ever started a game.

Deportivo La Coruña, March 2000 at Highbury

With a Spanish wife, I tend to enjoy victories over teams from the Iberian peninsular a little more. This was one of the best.

Bayer Leverkusen, February 2002 at Highbury

One of the finest home performances in a European match during Wenger’s first thousand games.

Middlesbrough 5 – 3, August 2004 at Highbury

At 1 – 3 down, many sides would have lacked the “resilience” to salvage a point let alone take all three. The unbeaten run continued thanks to this and it is worth viewing just for the gradual puncturing of the commentators enthusiasm for the day.

The final choice which was an excellent early birthday present

’til Tomorrow.

"On the first day of snowfall in the Kashmir valley this year, I decided to survey life on the famous Dal Lake in Srinagar early in the morning," says Your Shot contributor Maqsood Bhat. "While rowing my boat in the backwaters of the lake, I suddenly saw a little shop toward which a man was rowing his boat for some purchases. It was the only shop around, and it seemed to me that everyone was dependent on that little market for their supplies."

No, no, no… this isn’t how it works Arsenal. This really isn’t. It’s supposed to go…

• Plays badly
• Plays ok
• Plays superstar amazing
• Stalls on deal
• Speaks highly of Madrid
• Summer comes goes for big money

So what’s all this tying down players to mega contracts early so we don’t have a headache? It’s amazing, that’s what! Rambo has signed on until 2019, Cazorla has nailed his name to a 2017 contract and even the boy Zelalem has signed up on pro terms.

That’s almost the lot. All we’re waiting on now is Bacary Sagna and then it’s a 100% YES rate. Excellent work by the club. No messing around. No low balling. Just behaving like a proper club. Excellent work.

I think another interesting point about Zelalem is that in seasons past, he’d have played 45 games awaiting his first crushing injury. We’ve been able to hold him back. I’d loan him next season, like we did for Jack. That won’t happen, but it’d be nice for him to get a taste of hardcore football, even it’s only for 6 months. It’s character building, like when my dad used to make me go to B&Q as a kid… naked.

In other news, United overturned the mighty Olympiacos to keep their very unrealistic Champions League dreams alive. Ol’ Robin Can’t Be Arsied (look, I really tried there) banged in a hatrick before leaving the field in a crumpled injured heap. I don’t want to gloat, because it’s sad to see however, I did say last season he was the most expensive short term punt of all time. Sure, they won a trophy, which is more than we have, but that’s a helluva chunk of cash to spunk on a crock who is now proving his worth. You have to say, a United without a Robin is a United that is totally screwed.

I can laugh at the last bit, right?

Yes, yes I can.

Ha ha ha… chortle… snort… chortle

What is chortling? LOLing from the fifties? I reckon so.

Anyway, back to the game. Joel Campbell missed some chances and disappointed the world of Arsenal fans. Look, I hate to break it to people, but there’s a reason he’s playing with a Greek club at the moment. He’s not very good. Honestly, I know that’s a crazy premise, but if he was hot shit, we’d have him in La Liga, where he bombed, or in France, where he bombed.

Let’s not call for his return unless he’s smashing it up in a proper league. Arsenal need better. We don’t need kids and maybes this summer. We need prolific talent. God knows what the club are thinking, but there are plenty of names, Muriel, Draxler and Manzuckic… Let’s shop quality, not, oooohhhh some goals for Costa Rica 4 years ago and a goal against the worst United side in living memory.

There’s some talk about Arsene and his contract. Arsenal are confident he’ll sign it. There’s talk of Barca and PSG being interested. I’d be interested to see how he’d do at those clubs. Anyway, barring a total fail going into the final hurdle of the season, I reckon he’s staying on. They say he’s got £100m to spend. When doesn’t he? So maybe we’ll see some action. The squad really needs it this summer, tired legs, disgruntled exits, gaps that have been in the squad for two years. It’s a bloody expensive game is this football malarkey.

There are also rumours that Terry Burton is doing one this summer after being overlooked for the Youth Set up for Andries Jonker. A real shame, but if Andries is as good as everyone says he is, well, it’s the cost of progress and we shouldn’t shed tears.

Ok, I don’t have much more today, so I’m going to leave the room. But not before telling you that Peter Pan was an angel who takes kids up to heaven (Neverland). The kids were dead, people. That’s why they never grew up. Sorry to put that on you, but it’s really messed with my head. How could Disney commission such a monster of a cartoon?

Have a good day. If you can now.

Tombstone Territorial Park in Canada’s Yukon Territory is photographed using Kodak aerochrome infrared film. Originally intended for aerial photography to indicate areas of vegetation in surveys and to find camouflaged military encampments, this infrared-sensitive, false-color reversal film turns plant life a majestic red or purple hue while nonplant life often renders in gray or blue.

Well, what a weekend that turned out to be.

On Sunday afternoon the gloss was ever so slightly taken off the Everton win by the draw for the semi-finals which gave us Man City or Wigan. I’ll happily admit the ‘or Wigan’ passed me by. I never thought they’d be able to do again what they did in last year’s final, but they only went and did.

I spent the afternoon working on the book. I didn’t look at Twitter. I didn’t even consider the fact City might have gone out and only when I got a couple of texts did I realise what was going on. It now means that between us and a major trophy we have two games. One against Wigan, obviously, and one of Hull City or Sheffield United after that.

It is hugely reminiscent of the 2011 Carling Cup situation when there were three teams you’d fancy us to beat left in the competition, which is why I think there was so much fatalism around in the wake of the draw. Pre-emptive gallows humour, I guess. When I was looking for questions for today’s Arsecast Extra, there were a lot of people asking, ‘So how are we going to mess this one up?’

I don’t think it’s a feeling unique to Arsenal fans in any way, but down the years we’ve had enough moments to make anyone just a little bit wary. West Ham 1980 (Damn you, Brooking), Luton 1988, Birmingham in 2011, and you have only have to go back to last season to recall defeats to Bradford (ugh) and Blackburn. If that doesn’t inform your thinking then you’re a better man or woman than I am.

But, let’s be honest about this: not winning the FA Cup from this position would be rank failure. Of course we can’t underestimate a Wigan team that have won the cup and twice beaten Man City inside 12 months. Nor should we take either of the two other sides for granted should we progress to the final in May. But when you look at the calibre of opponents you really couldn’t ask for much more.

We’ve done our bit beating big sides. Dispatching Liverpool, Everton and Sp*rs on the way to Wembley is plenty, and while I’m all for the excitement of winning against top opposition, I’m also a huge fan of the mundane and routine. And with all due respect to Wigan, Hull and Sheffield United, those are teams you would, and should, expect Arsenal to beat 9.9999 times out of 10.

The good results we’ve achieved in our own games have been rewarded by draw that is beyond favourable. We’re the absolute favourites for this competition and so we should be, given our stature, resources and playing squad. Unlike tomorrow night, for example, where we go to Munich as underdogs, with nothing much to lose, the weight of FA Cup expectation is on us.

It’s a kind of pressure – especially in this period without having won a trophy in so long – that we haven’t always been able to deal with. But I think we’re better suited for it this time around. If you want a longer answer as to why I think that, tune in to today’s Arsecast Extra (out around lunchtime), but basically it’s down to having better players, better characters and being motivated by the desire not to fail as much as to win.

It’s beautifully set up for us and perhaps allows us a certain freedom in our upcoming games in the league – almost like a safety net. The trick now is to make sure we don’t use that too early, there’s still so much to play for there, but the FA Cup now gives us a wonderful opportunity to get rid of that monkey on our back. And it’s a twat of a monkey because not only is it uncomfortable, people keep reminding you there’s a monkey on your back and when they do the monkey does a bit of wee in your ear. Stupid monkey.

For now though, we have to stick the cup in the compartment entitled ‘Later’ because there’s plenty to be going on with in the meantime. Obviously tomorrow’s Champions League clash with Bayern Munich is going to be a tough one, but the renewed Mesut Ozil gives us that little bit extra in attack and hopefully he can deliver again after his weekend display.

Arsene Wenger has admitted the penalty miss in the first leg affected him badly:

Psychologically sometimes the wound is like a physical one. You can talk and talk and talk but it takes time. You just have to leave it to time. I think he is over it.

And he’s urged the German to find the right balance between his creative and goalscoring side:

At the moment the balance is a bit detrimental to the finishing. His strong side is providing. But he is pacy – much quicker than people think – and with that technical quality and that pace, if he gets into the right areas and with the service we have, he can score goals. He wants to score more goals, I am convinced of that.

I know many people have bemoaned the lack of a 30 goal striker in this team, and there’s no doubt adding some firepower is going to be high on the summer agenda, but the ability to share goals around the team is going to be just as important between now and the end of this campaign.

Ozil is certainly capable of scoring more. There have been times when he’s in a position to have a crack and he chooses the pass, and maybe that’s where the manager wants him to be a bit more ‘selfish’, if you like. Between now and the end of the season you suspect that some Ozil goals will go a long way to helping us achieve what we want to achieve.

Right, that’s that for this morning. The Arsecast Extra was recorded last night and will be available for you before lunchtime.

Back tomorrow with a Bayern preview and all the rest.
