Schalke's Klaas-Jan Huntelaar: I know nothing of alleged interest from Manchester United

Out of contract in the summer of 2013, the 28-year-old Dutchman has indicated that he is willing to talk to the Bundesliga outfit regarding extending his deal, an objective that general manager Horst Heldt stated is on his agenda earlier this month.

However, if terms cannot be agreed, the Germans may feel it wise to cash in on the striker before his value starts to depreciate as the end of his commitment nears.

"I know nothing of alleged interest from Manchester United," Huntelaar, who has scored 15 goals in 16 league appearances this season, said to Voetball International. "I will not even speculate, I am concentrating fully on Schalke."

"I'll let any offers come to me quietly and will then see what happens. This is the attitude I’ve always had.

"My contract runs until the summer of 2013. If they [Schalke] want to talk, I'll gladly listen."

Schalke presently lie third in the German top flight and will be keen to hold onto their top scorer as they continue to battle for a place in next season’s Champions League.
