Kuszczak told MUTV: “Every club has two or three great goalkeepers, so I just have to wait.
“When I play, I want to prove to everyone – the fans and the manager – that I can be the best and I can be number one. That is all I can continue to do.
“Throughout my career, all I have done is try to improve. I am more critical of myself than anyone else. The day I think I cannot improve is the day I start to go backwards.”
