I'm hopeful he starts today in a back three with the two young lads (but more-so because that means we can leave Smalling and Jones out to hopefully avoid rushing them into playing too many games after recent injuries). Once we have some midfield players back and the defenders fit, I'm confident that Evans will be left out of the team in favour of Smalling/Jones and Rojo, with Carrick being the deep midfield player in a diamond who slots into a back three when needed. Evans' only saving grace and the reason he's been in the team so much for my money is that he's not as injury prone as the rest (seemingly). Sure, he's had his fair share of injuries too, but actually being fit and available is one of the most important things to get any kind of consistency going (although he's been consistently bad or average IMO for about a season and a half at least).
At the moment, without trying to be too harsh on the guy, I think he's the most likely out of our current defenders to move on in the Summer.
