Walcott is officially the real deal. His little dink was delicious. I suspect he will be signing a new contract rather soon. You can you want to play through the middle all you like, but the best way to do so is by putting in performances like that.
Still, Arsenal have been getting lucky this season, especially with penalty decisions. If either Wilshereor Cazorla gets injured they are screwed, they have no squad depth in the middle of the park. Not sure how much longer this good run will last, especialy with the City game coming up.
