Nasri if anything has declined. Glad we sold him, plus he's a ****. Cole obviously has done very well, but the "family club" atmosphere to develop players is all fine and good but only seems to get you so far with the competition now at the top of the league.
Perhaps RVP just sat down with Wenger + the chairman and they told him their summer spending was going to be limited; so Wenger replaced him with Giroud in the anticipation of him leaving either this year or next, and picked up Podolski to replace Arshavin. That'd be more in line with Wenger's recent spending, that is to say, little first class depth in any position.
Slightly dissapointed he came out and said he's going to not sign a new contract, not because he deserves trophies, as he does (the Dutch national team certainly arn't filling in those gaps!), but because the club could have done with selling him for as much as possible to strengthen the squad. Perhaps he'll see how this season goes, if we win nothing (again) he will be off. That'd be pretty fair I'd say, he's given us some of the best years of his career.
