I love Evra, but I wouldn't be against him being sent to Monaco/PSG and a 15mil or so transfer for Baines.
I would however like to see Buttner/Fabio come on a lot, though. I hope Fabio can do a Rafael.
It was stated by a few during the original transfer that Fabio was the better player. I know Fabio hardly got a chance behind Evra, and I didn't hear great things coming out of QPR last season (although I didn't see him playing myself that often), but I just cant see him progressing to the quality required unfortunately.
Buttner is a reasonable understudy for another season - I just hope he gets a good run of games in the cups / and "easier" league games to see if he can really push on in his 2nd year.
