German international defender Manuel Friedrich is still undecided as to whether he will leave Mainz at the end of the season.
The 27-year-old is contracted to the Bruchweg Stadion outfit until June 2008 but media reports claimed he had received several offers from other clubs.
However, Friedrich is yet to make a final decision on his future and insists he could extend his stay at Mainz.
"I have not yet said that I will be leaving," Friedrich told Kicker.
"I'm still thinking things over - whether it would make sense to move to another team or to commit my future to Mainz."
Friedrich admits Mainz coach Jurgen Klopp will play a major role in his final decision.
He added: "If he says there is no point me making a move, or joining a particular club, then I will listen to what he has to say."
