Kuszczak wants to be Man Utd No1
"It was a good exam for me over Christmas and I think I did quite okay. I certainly did my best and I tried to help the team win our games."
Although Kuszczak is acutely aware of his understudy status, he insists being at Old Trafford is beneficial to his career.
"Every single game I play for United is a step forward," he said. "I feel more comfortable and confident each time I play and that's what a goalkeeper needs. The Champions League experience has been very good too, so I think I'm on the way up."
Van der Sar may be Sir Alex's current first choice but Kuszczak says he hopes to one day dislodge the Dutchman from the number one spot.
"I'll do everything I can to push Edwin for the jersey and I think that helps both of us. We have a good relationship and there's healthy competition on the training field."
