I think so (sure I read it somewhere). I've also read that he wants to finish at Chelsea, but he has definitely said that he wants to see out his current contract.
Schurle is a good player and a good signing. I see him as an attacking midfielder more than a striker (although he can play there as you say), so that's another AM to add to Oscar, Mata, Hazard, Moses, Marin lol! Although I expect that Marin will leave. I think an attacking force of Torres, Ba, Lakaku and Falcao is pretty good looking one.
With Mourinho coming back though (assuming he does of course), I'm curious as to what he'll do with the formation of the team. I wonder if he'll take them back to playing the diamond that he made successful before or stick with the 4-2-3-1 formation that Chelsea have perfected this season.
I think Felaini is awesome. He's unplayable on his day. It's just the amount of fouls that he gives away that worries me. I'd rather someone like Cabaye (hoping that Newcastle get relegated for this to happen ) or Moutinho. Someone in the Paul Scholes mould.
