Cesc had shit around him all over the pitch. Lehman on decline only to be replaced by Almunia then Chesney. A terrible backline from Gallas, Toure, Vermaelen, Eboue, Clichy, Traore, Djourou, Senderos. Sagna was the best defender he played with. Kos played with Cesc but wasn't good until he formed a partnership with Merts.
I mention Eboue in defence but remember when Wenger would play him on the right wing?

Gilberto was on the decline as well and could hardly pass the ball forward. Rosicky was often injured. He'd often be playing with Diaby, Denilson, Hleb and Nasri in the midfield. Walcott was often poor.
Up front we at least had strikers with some pace. But let's not forget the games where we were depending on Bendy and Chamakh! RVP was often injured and after one good season where we came close to winning the league, Ade fucked off shortly after. Giroud is a different striker but not shades below some of the guys we were used to seeing.
I'm amazed we finished top 4 with some of those guys when I think about it. But then again, the standard in the Prem was piss poor. But I still enjoyed the way we played. With unknown and inexperienced players, we really put the beating on some teams.
