The former City keeper wrote in the Daily Mail: "He is a fantastic goalkeeper. He does make many mistakes, but people are looking for the mistakes rather than seeing how good he really is. He had 18 clean sheets last year - 18! That's six more than Man United had. Eighteen clean sheets in a team that wasn't working. I think that's pretty good. Be nicer to Joe.
"Last season when he conceded Robin van Persie's winning goal in United's 3-2 win, he got the blame.
"The manager went on the pitch afterwards and tried to defend himself by going out and blaming Joe.
"The ball was going to the near post, as a goalkeeper you make your move then. It gets deflected and goes in at the far post. He gets so close to it, it would've been the best save ever had he got to it. But how can he ever save that?
"England have got a great goalkeeper. He's one of the best you've ever had."
