Peter Shilton: "It's only tough if you let it affect you.
"He's got to show the true character of a top keeper and I am sure he will do.
"Forget the criticism, get out there, train hard and look to the next game to prove people wrong.
"Something has happened in the last year. I don't know whether he has lost his focus, but he's not quite the Joe Hart who burst on the England scene. That's obvious.
"There have been quite a few mistakes but some terrific saves as well.
"He is the best goalkeeper we have at the moment, though his form has dipped.
"We don't want to be changing the defence around going into important games.
"There are things he could improve upon (in technique), but because of his natural confidence, his agility and his natural reflexes he compensates a bit for that.
"But room for improvement is a good thing in a young goalkeeper.
"I don't think it's right that I should be giving him a goalkeeping lesson in the press leading up to two World Cup games but he has proven he has got the ability to do well.
"He's had some good games for England, in Brazil he had a great first half. All I'd say to him is be more determined and work hard in training.
"He should be setting his own standards.
"He shouldn't have to be pushed by competition. He should be pushing himself. He needs to get back to the form he was in when he came into the England side. We need a really confident Joe Hart."
