Diving into contention: Tomasz Kuszczak was handed a rare start against West Brom
Kuszczak, 28, has struggled to make an impact since arriving from West Brom four-and-a-half years ago. The Pole replaced flu victim Van der Sar against his old club on Saturday, but it was his first Premier League appearance in a year.
He said: 'It was my debut today - the first of January! Of course I would like regular football. I need to see what the boss wants to do, whether he wants to play me or sell me. But definitely I want to play.
'Every player has his ambitions and I have mine. I have sat on the bench for five years and I need a chance to play more than one game in two or three months. You can't prove anything like that.'
Kuszczak has not spoken with Sir Alex Ferguson about the situation, althoughthe indications are it will be Ben Amos who is released on loan this month tofurther his education.
'I will wait to see what happens at the end of the season,' said Kuszczak. 'I need to see what the boss wants to do - whether he wants to play me or sell me. At this present moment, I don't know.
'Edwin is 40 already. Who knows how long he can play? It may be his last season. But a club like this needs to have young goalkeepers coming in.
'I want to play but it is not in my hands.'
