But he insists he's happy on Tyneside.
"There are rumours. I am following it a little," he told France Football. "But I have four years remaining on my contract with Newcastle.
"Today I don't want to know anything. That is what agents are for."
He added: "At Newcastle we will play in the Europa League.
"The atmosphere is already huge at St James Park with us in the Premier League and it seems stronger now we're in Europe."
