Chelsea boss Jose Mourinho has rejected claims that he has faced dressing-room unrest over the contribution of German summer signing Michael Ballack.
Jose Mourinho has pledged to keep playing Michael Ballack
Reports in the English and German media hinted at disquiet about his form.
But speaking ahead of the Carling Cup semi-final with Wycombe, Mourinho said: "Reports about problems in the dressing room are not correct."
And he added: "Do we want more from him in terms of performance? Not from him, from everybody."
Mourinho also warned that he would not be pressurised into changing his team.
He said: "If the objective is to put some kind of pressure on me then no chance because I pick the team, nobody else does it. Press opinions, other player opinions are not for me.
"He plays against Wycombe and I hope it is the first step for him to play his first English cup final."
