Manchester United boss Alex Ferguson was angry with Lille players' reactions following Ryan Giggs late winner in their UEFA Champions League tie on Tuesday. The Welshman struck home a quick-free kick three minutes from time whilst Lille keeper Tony Sylva was organizing his defensive wall. Lille players protested the referee's decision to allow the goal to stand and threatened to walk off the pitch. "I think UEFA have got to take some action, I've never in my life seen anything like that," Ferguson told ITV Sport. "It'll maybe take an hour to digest it exactly, but I can't understand it. It's a disgrace, what we've seen tonight. That's not football. "The Lille staff encouraged their players to come off the pitch. It's intimidation of the referee and it's made for a hostile atmosphere inside the ground. I think it's a disgrace." The Scottish tactician was also unhappy with his players' interference in the matter. "It wasn't our concern. It was for the referee and the fourth official to decide what to do." I wanted our players to stay on the pitch but instead they started milling around with their players. We don't want that."
