Birmingham keeper Butland eager to avoid comparisons with Man City's Hart
Team GB No1 Butland gaffed during last night's Olympics defeat to South Korea.
Before the game, he said: "I enjoyed being part of the England set-up because I gained so much experience and hopefully that will continue.
"But I am still only 19 and I need to play games before I can ever think about testing Joe because he is one of the best keepers in the world at present.
"All I want to do at the moment is enjoy this Olympic experience and see where it takes me."
