Schalke manager Felix Magath insists Manuel Neuer will not be sold in the winter transfer window, but the Germany goalkeeper is keeping his options open.
Amid Schalke's disappointing Bundesliga form, the shot-stopper has been linked with Bayern Munich and a host of other clubs from around Europe.
But Neuer is under contract until the summer of 2012 and Magath, who has guided his club to a date with Valencia in the knockout stages of the UEFA Champions League, has no plans to sell.
He told Kicker: "Manuel Neuer is under contract at our club and he will definitely remain with us until at least June 2012.
"Of course, we would be able to sell him for a vast sum of money. But we would not be able to pick up any equal replacement afterwards."
Gelsenkirchen-born Neuer, 24, also insists his full focus is on Schalke, who were considered to be title contenders in pre-season but sit in 10th place at the winter break.
He said: "It is a fact that my deal is valid until June 2012. There will be no further statement about this from my point of view. I just care about Schalke."
But asked if a summer move was out of the question, he said: "I don't believe so."
