Reds boss Rafa Benitez is prepared to offer £6 million to prise the Argentina international away from Old Trafford.

"I still don't know what I am going to do in the future, and I'm going to start thinking about that after the Copa America," Heinze said. "The interest in me from important teams such us Liverpool, Juventus and Real Madrid makes me feel proud.

"But I feel very comfortable in Manchester, and I'm very grateful for everything I've experienced there."
