Goalkeeper Tomasz Kuszczak says he has become a 'slave' to Manchester United and reiterated his desire to leave the club in January.
The Poland international, 29, revealed over the weekend that Sir Alex Ferguson had blocked a proposed loan move to Leeds.
Kuszczak was keen to join the Championship side on a deal until the end of the year to keep himself in national coach Franciszek Smuda's thoughts ahead of next summer's European Championship, which his country will co-host with Ukraine.
He is not happy that United made him stay and hopes the club will reconsider when the transfer window reopens.
"I've become a slave to Manchester," he said.
"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."
