The London club are ready to move in January in a bid to boost their strike force. Rookie boss Andre Villas-Boas has severe concerns over misfiring hitman Fernando Torres.
A source close to the player said: "Higuain is unhappy at being left out all of the time. He wants to fight for the title but was on the bench against Barcelona at the weekend when Real lost 3-1 and he knows where his place is now.
"He would be interested in what people have to say to him."
