Hazard to Manchester United?

At the Lyon vs. Lille game, there was an unexpected watcher, Sir Alex Ferguson. He was reportedly watching Eden Hazard. Could this mean a that Hazard may be joining United? I feel United have enough wingers as is, but if Fergie is planning on playing him as a CAM, then I feel it would be a great addition to the squad.
However, there has also been links with other Premier League teams and Hazard. In these clubs he has been linked with, the stand out is Tottenham. I feel if Hazard joins them, they would become a killer team. They would have Bale, Modric, Van Der Vaart, Hazard, Parker, and Saha! Hazard joining the Premier League could seriously up the competitiveness of the Premier League.
What do you think? Will he come to United? Or any other club for that matter in the Premier League? Will he stay with Lille? How will this effect the Premier League?
