Schalke have revealed that they are open to the idea of parting with Jefferson Farfan during the January transfer window but only for at least €10million.
The Peru international's current contract with the German club expires at the end of the season and he has been linked with a number of teams.
The Gelsenkirchen-based club admit that they would be interested to hold discussions with potential suitors for a transfer during January but only at a certain price, while disclosing that no official offers have come in yet for the 27-year-old.
"Jefferson Farfan is a key player for our club," Schalke general manager Horst Heldt told Reviersport newspaper.
"Therefore, I would reject any idea like another club coming in the winter transfer window to offer us a compensation of €1million for a deal involving him.
"Still we have to think twice if there is a club lining up a bid that feel that money is not an issue, like Anzhi Makhachkala of Russia for example.
"If such a club offer €10 million or more, we would have to consider that.
"We are aware that there are clubs considering Jefferson Farfan, but we have yet to receive a bid for him from any other club."
