The defensive midfielder lined up against German giants Bayern Munich in their Champions League encounter on Wednesday.
Just last month he was questioned on a move to Old Trafford where he revealed he "wouldn't hesitate" to make the switch.
He said: "If it was as concrete as was being said, if they wanted me at all costs, I'd already be there. When you play for Anderlecht and you have the chance to go there, you don't hesitate, but Anderlecht had their bit to say. Everyone had to agree."
