William Gallas has spoken out about the rumours linking him with a move from Stamford Bridge in the summer.
Gallas has being forced to play out of position, at left-back in recent matches and is know to be frustrated by this.
But speaking in a French newspaper, the defender hit out at suggestions that he will leave the blues in the summer.
"It is not true I may leave," Gallas, 27, told French newspaper L'Equipe.
"But although I will sacrifice until the end of the season, we'll then have to clarify things once and for all."
Gallas has had to play left back as a result of regular defender Wayne Bridge's injury.
With Celestine Babayaro sold to Newcastle, Chelsea don't have a recognised left sided full-back to call on.
Gallas had previously lent weight to the notion that he could be on his way.
he is reported as saying:
"Of course, I know that with the injuries the manager has no other solution than to play me on the left and I can accept it for the moment," he added.
"But it's very difficult. I never feel as if I've given my best.
"I will go on in that position until the end of the season but then things must be clear. I don't like to play left-back, I am not comfortable, I am not at my best and it has to change."
