Evra did okay last season, I think people rate him higher than he really did though, he scored a few goals yes but defensively he didn't look as sharp as he was a couple of years ago imo.
Baines is a sensible replacement, if we can get some money for Evra who isn't getting any younger and replace him with Baines then I think that would be a very sensible bit of business for us, particularly as Baines is at his peak whilst Evra really isn't anymore (imo)
