Also: Evans would be missed because his great form with Vidic, Rio and Evra, but no mention of Rafael's great form with the same players, when he was arguably the best right back in the league. Seems like he is posting with an agenda if he's using historical form for one repeatedly injured player but not another.
The fact is, you cannot make an argument for keeping Evans while making an argument against Rafael. They have both shown themselves to be United quality in the past but have both suffered with lapses in form and routine injuries since then. The thing in Rafael's favour is that he's at least shown glimpses of his class in the past two seasons. Also, we only have one right back, whereas we've got a bunch of CBs. Fair enough, they are unreliable because of injuries or inexperience, but we're talking about squad players. I think we're all in agreement that we should be buying at least one experienced defender.
