Former Manchester City winger Peter Barnes is convinced Jose Mourinho knows he blundered selling Kevin de Bruyne as Chelsea manager.
Barnes wrote for the Daily Mail: "Colin Bell was the best I ever played with, but Kevin De Bruyne is as good as Bell if not better — and that's a hell of a statement coming from me.
"He's the total player. When he plays well — and he does most weeks — Manchester City play well. He can make anything happen. De Bruyne cost £55 million but when you think what Manchester United paid for Paul Pogba (£89m) across the road, he was an absolute steal.
"Jose Mourinho sold him at Chelsea and I bet he's kicking himself now when he sees what De Bruyne is doing for City. He was a young man then but he did well playing in Germany and City are seeing the rewards."
