Macheda's loan ends this week.
"I'm on my final year of my contract at United so I'll see what happens in January," he said.
"I have to go back at the end of December but we'll see what I am going to do after. I have not spoken to anyone."
He went on: "It is important to finish the loan spell with a few good games, a few good results especially if we win - that is the most important thing."
