The Argentinian scored the first goal for United in their 2-1 win at Wigan on Wednesday night.
Ferguson told Sky Sports after the match: “He is a fantastic player.
“He knows I want him to stay. I had a chat with him today and (chief executive) David Gill has had meetings with him.
“I’m sorry I have to keep on going on about this, it has never changed.
“(The fact) we’re not negotiating with a football club is the problem – we’ll see.”
