The 27-year old Scottish striker is to be the subject of a third bid from the Teessiders and is aware the Whites may offload him if the price is right but says he would love to remain at Elland Road if it were possible.
“If the club were to give me a longer contract, then I am more than happy to sign it. Whether that comes or not could be a different story,” he said.
“I know there are other teams interested in me, but I am very calm about the situation. Whatever is going to happen will happen.
“The main thing is that I am very happy here and focused solely on Leeds United.”
