Watch any game he's played in when the opposition move the ball quickly and then come back and say he's brilliant positionally. Against the rs he's been caught out so many times over the years, cos he doesn't have the legs. It's one thing standing still between the centre halves, it's a whole different thing closing people down when they're running towards your centre halves.
He uses the ball well most of the time, I'll give you that but it's arguably the easiest area to use it in, cos he comes so deep most of the time he's almost a defender, and then you're up against forwards. Or he's coming from deep with most of the players in and around the area, meaning he's got 10 yards of room to pick someone out. It's the michael carrick thing. People see some decent passes now and again and suddenly think the player is great. When the reality is when your side is really tested the player becomes a passenger.
A player shouldn't need the right system, the right game etc. to perform, we should be demanding they can perform week in, week out.
I can understand Koeman respecting him, Barry has worked hard to have a good career and Everton seem to want to help him to break Giggs' record, but personally I think he'll be gone closer to the end of the window.
