I thought Sanchez would enjoy playing in Ole's attacking, pressing system, but he performed at the same low standard he did under Jose. If he did manage to find his Arsenal form or somewhere approaching that level, then he would be like a new signing. Unlikely to happen though.
I'm unsure about Fred. He's shown glimpses of his ability, on occasion, but I cannot recall a single performance of his where he was solid throughout the game. He gets caught in possession a helluva lot for a player who was supposed to be composed and technically gifted.
Matic looks finished in all honesty.
Gabriel Heinze aside, we've had some piss-poor luck with South American players, it'd be nice if one were to turn out a success.
