"Norwich are growing in their belief in the last 15- 20 minutes. There is talk of Arsenal winning the title but they need to be putting sides like Norwich to bed."

This one is really opening up.

That is a fantastic save from Petr Cech. 

A Norwich cross finds the heart of the Arsenal penalty box, it evades all the yellow but Gabriel inadvertently heads on goal, but Cech is there with a low, strong hand.

"Arsenal have lost a little bit of attacking momentum with Sanchez going off. They do not seem to be as effective going forward now."

One goal here would put Arsenal level with Manchester City and Leicester at the top of the table, but at the moment it's looking a world away. 

With Alexis Sanchez off the pitch injured, who can they look to to turn this game? 

Norwich, meanwhile, are zipping it about with a growing sense of assurance...

Especially with the small matter of reaching the Champions League group stage to get through...

"So Arsene Wenger says before the game that Sanchez had a hamstring problem but still risked him - a gamble that has backfired spectacularly."

At this rate you might be in for a game Mo. Any good in central midfield?

Joel Campbell looks good down the right here, silky even in his dribbling...

But the cut-back goes nowhere and here come Norwich with the interception...

Arsenal are having to scrap for this and dig back in to shore things up. 

Arsenal are on the ropes a bit here. 

Two men off injured, and Norwich are sensing there may well be three points for them in this.

Gary O'Neil spoils the mood though, blazing WILDLY over as his own corner pops back to him. He's never scored for the Canaries.

Big boots to fill. 

Joel Campbell is indeed on for Alexis Sanchez. He'll presumably do the same job, but as well as the Chilean can in full flight? 

Nobody comes close.

The injury curse strikes again (again)? This is getting silly.

Alexis Sanchez is hobbling, it looks like a muscle problem and a real problem. 

Laurent Koscielny has already gone off, and Joel Campbell is now getting ready to replace Sanchez.

How many times?!

Mesut Ozil hits it straight into the wall. There so seldom something to get excited about, and we do. Moths to a flame.

Now then. 

Gary O'Neil goes in the book - he halted Aaron Ramsey's driving run - and as Ramsey went down he scythed into a waiting Norwich pack.

That's O'Neil's third booking in as many games. Free-kick in a decent position...

This is not Santi Cazorla's finest moment - he's booked for a dive. 

I have seen a lot worse (for worse, read acrobatic) but fair play to the ref for calling him up.

Scrappy, bobbly but so close to a goal for Arsenal. 

Alexis Sanchez dinks one in and John Ruddy has a rush of blood, he's out and swipes but misses, the balls lobbing about but Norwich hook it clear, with Mesut Ozil threatening to prod home from close range.
