Schalke striker Klaas-Jan Huntelaar remains confident he will be fit for the World Cup finals despite a fresh setback.
Huntelaar was ruled out in October after knee surgery - but Schalke had hoped he would return for winter training in January.
However, the Dutch international has suffered a fresh set-back and his return has been put back by at least another month.
"The aim is to be back training in February," Huntelaar confirmed to Dutch daily De Volksrant.
"If I'm fit, I'm sure I'll go to the World Cup. We'll have to wait but I'm only thinking positively."
