I don't think he'll win a trophy this season, as i think City are just too strong and relentless when it really matters just now, and i think there's still some question marks over the Arsenal squad in terms of quality / fitness. I think as a group they are starting to believe they can beat anyone on their day, but i don't think they have the same relentless drive that City do quite yet over a 38 game season.
It's a strange season in many ways. Last season because of the first 6 months, expectations were raised massively, which has meant this season everyone including Arsenal fans have been comparing this season to last, but 50 points at the half way stage just skewed everything.
This season has been more steady this far, obviously not quite hitting the heights of the first 6 month of last season, but trying to make everything a bit more solid and stable, and more controlling. I think this will benefit the team over the next couple of seasons more.
The FA Cup exit has been the black mark on the season for me so far, i was disappointed to go out so early, but that was a game settled on fine margins, we didn't take our early chances and got suckered punched right at the end.
