Arsenal manager Arsene Wenger has called on Lukasz Fabianski to prove he is a "world-class goalkeeper" by helping dump bitter-rivals Tottenham out of the Carling Cup on Tuesday.
The 25-year-old is set to get a chance to win over the critics as Wenger rotates his team at White Hart Lane.
Despite making several high-profile errors, Fabianski continues to retain the faith of his manager, who is hoping the stopper will repay his faith.
"I am personally convinced he is a world-class goalkeeper, potentially, and of course when you have that potential you want to transfer that into competitive games," Wenger told Arsenal TV Online.
"I believe he has a very strong attitude, very strong response and he works very hard in training, so he has an opportunity to show his massive talent.
"I have massive faith in him and I think I have shown this historically - I am convinced he will become a great goalkeeper."
