Tonight's Carling Cup tie will be the Pole's first appearance of the season and he told Manchester United Radio: "I'm really looking forward to playing. For me, the season only really starts now.
"This is a good opportunity to show everyone what I can do. I want to show people that I'm working hard and that I'm good enough to play for Manchester United."
The ex-West Brom star added: "Of course there is some frustration when you're always on the bench. Nobody likes sitting on the bench but I have to be patient and remain focussed. I need to train hard so I am ready for whenever I'm called upon.
"The season is long and we've got a lot of games. Last season proved how important it is to have a big squad and I know I'll get my chances."
The 25-year-old says he's hoping to follow Edwin van der Sar's lead and keep a clean sheet tonight, although he admits he won't mind too much if Coventry make a game of it.
"Usually it's better when you have nothing to do, but it's my first game back so I want to show everyone what I can do. I'd like to produce a few good saves but still keep a clean sheet. Another 2-0 result would be perfect."
