Considering Gallas is off in a year, we now need 2 CB's. considering Gallas is off, we could easily have kept Toure, bought another CB who could play/be in rotation when Toure was away and get practice/used to playing all year. Then end of the season we'd end up with Toure, Verm and guy number 3. Instead, with the squad as it is now, end of the season we'll have Verm(yet to be proven as good) Djourou, Song, Senderos, thats assuming Senderos isn't sold as I still think he will be, he certainly will be IF Wenger buys someone good, though for you hopeful people thinking he'll buy, I think he's just going to turn to Senderos/Song.
Losing Toure is a joke, its not a bad price for someone whose in the last year of his contract, its a terrible price for someone you should be keeping for the next 5 years though. Oh wait, theres they guys kidding themselves he's worse, other than the fact that last year he was outstanding with Gallas, and this year he was barely played till he threatened to leave and was instantly a formidable partnership with Gallas again.
Joke all around, so is getting rid of Eboue. We have no pace in midfield, 2 central attacking midfielders on the wings and not even hugely pacey strikers(looking at Arshavin/Rosicky wings I guess). Only Theo has pace, horrible winger, "might" turn into a good striker. Sagna, CLichy, Gibbs, not sure theres any genuine pace in the squad anymore.
Toure and Eboue, both who should have been tried at DM last year and weren't, both moving off, so more first team Song/Diaby, woo. I still don't think we'll buy, I think Song will be Wengers answer for defense and Diaby to be used as Eboue was, right/left wing when others are injured/tired.
