Wenger deserves a lot of credit for many things that are going right atm but I have absolutely no doubt that Wenger has utterly fluked this. Wasn't considered good enough by Wenger or Ferguson and yet Welbeck is. Shows how fine the margins are at the top level. Timing of opportunities is everything. Think he has been consistent for long enough now to prove that this is his level. And if that's the case, you wouldn't swap him for any DM in the league right now. Coquelin and Bellerin becoming top players have really transformed the quality of the first team.
