Goalkeeper Tomasz Kuszczak has claimed he is being treated like a "slave" by Manchester United after a proposed loan move to Leeds was blocked.
The Poland international was keen to join the Championship club to boost his chances of selection for Euro 2012.
But according to the 29-year-old, his request was turned down by manager Sir Alex Ferguson.
In comments reported by a number of national newspapers, Kuszczak said: "I've become a slave to Manchester."
The Pole added: "I'm frustrated but I don't want to slander or criticise Ferguson. It's not my style.
