Goalkeeper Tomasz Kuszczak has claimed he is treated like a ''slave'' by Manchester United after a proposed loan move to Leeds was blocked.
Kuszczak, 29, was keen to join the Championship side on a deal until January to keep himself in Poland coach Franciszek Smuda's thoughts ahead of next summer's European Championship, which his country will co-host with Ukraine.
In comments reported by a number of national newspapers, Kuszczak said: ''I've become a slave to Manchester. I'm frustrated but I don't want to slander or criticise [Sir Alex] Ferguson. It's not my style.
''I've talked to Ferguson recently. I asked him to let me leave the club now, before the January transfer window. I told him I want to play and get back into the national team, because Euro 2012 is just around the corner - but it seems he doesn't care.
''The possibility of a two-month loan to Leeds United came up two weeks later. The club blocked it.
''It was a glimmer of hope for me. It would have reminded the Poland manager about me - but I didn't get the club's approval. I have respect for Ferguson because, for me, he's a great manager, but I hope he will let me go in January.''
