This man will be key to their breakout speed.
If there's one thing Arsenal have lacked this season, it's that cutting edge. That decisive play that they used to be known for. The ability to slot passes all around the pitch, stretch their opponents out and then jump on that one opportunity when they have their guard let off.
The Arsenal of this 2011-2012 season have looked slow, lethargic and just genuinely uninterested. I'm sure there are bound to be a few problems with new teammates getting into the grove of things, but it really shouldn't be taking this long.
What Arsenal need to do against the Black Cats is come out of the gates flying. They need to pound it down the wings, play it across the top of the box and play in Sunderland's defensive third.
If they start out with a high tempo in the first 25 minutes, then they will ruin any sort of momentum Sunderland were hoping to carry into the match.
But they shouldn't stop there. They need to be efficient in their play as well. They need to play smart passes and always be looking for the open space.
As any professional team should be.
