Laziness has nowt to do with it really - he chases down the ball, but that's about all. I could go on the pitch and do that for 90 minutes, no bother. The problem is how little he actually contributes from a footballing perspective. He doesn't hold the ball up, link the play, make effective runs, win headers, pass the ball well, have any capacity to beat a man, and so on... Worse still, he rarely even shoots these days... He's tremendously ineffective.
Disagree with that like, he made some decent runs in behind their defence today but the flick on/pass was usually poor. We got a half chance from a floated diagonal to him on the right where he brought it down brilliantly and got past the defender. Problem was we didn't have anyone in the box for him to get the cross into and he stupidly decided to take a second defender on. Still don't know why we float the ball to him when he has his back to goal though, he's useless in those positions.
