Lille have lodged an official complaint with Uefa about Manchester United’s winner in the first leg of the Champions League tie on Tuesday.
Ryan Giggs scored from a free-kick as Lille were still lining up a wall and the French side were unhappy that referee Eric Braamhaar allowed the goal to stand. At one point it looked like the Lille players were going to walk off the pitch in protest at the decision to allow the goal.
Lille president Michel Seydoux insisted his players would not have walked off the pitch.
“It was not an attempt to get the game abandoned – it was an emotional moment,” said Seydoux.
However, United boss Sir Alex Ferguson branded Lille a “disgrace”.
“I have never seen that before in all my years in football,” he added.
“The Lille staff encouraged their players to come off and that made it a hostile atmosphere inside the ground. It’s a disgrace.”
Uefa will discuss Lille’s protest and the behaviour of their players during the match on Friday.
