Kuszczak is now in his sixth season at Old Trafford but will be making only his 53rd appearance when he lines up for Wednesday night's Carling Cup tie at Scunthorpe.
As Edwin van der Sar's standards show no sign of dipping despite the Dutch veteran approaching his 40th birthday, and speculation persisting about possible replacements when he does eventually call time on his stellar career, it could be regarded as an unsettling time for Kuszczak.
The 28-year-old Pole is remaining focused on his immediate task.
However, having seen Ben Foster prosper since he quit United for Birmingham in the summer by winning his place back within the international fold, Kuszczak realises he may eventually be forced to reach the same conclusion.
"I could understand Ben's position," Kuszczak told the Manchester Evening News.
"He wanted to move because he wanted regular football and he wanted to play for England.
"But if I don't get enough games I will have to do the same as Ben.
"The years are going by and I will be 29 after this season. I want to enjoy football and I want to play."
