Lille were furious with the referee's decision to allow Ryan Giggs to take a quick free-kick which earned Manchester United a 1-0 win.
Giggs struck seven minutes from time in the first leg of the UEFA Champions League last 16 encounter at Lens' Felix Bollaert ground.
The Welshman took the set-piece as Lille were busy arranging their wall and coach Claude Puel was unhappy with Eric Braamhaar's decision, claiming he wanted to bring on a substitute before the free-kick was taken.
"It's incomprehensible. We wanted to place the reserves (substitutes), of course the referee didn't want to," Puel told French television.
"He didn't find a delegate (official) either on the bench."
Lille almost walked off in protest at the decision, with captain Gregory Tafforeau also critical of the official for allowing the quick free-kick to stand.
Tafforeau said: "When the goalkeeper asks to place his wall, you should wait for the referee's whistle.
"There was no whistle at all and the player shot directly. The result is (a) goal."
The French side also had a goal disallowed, after Peter Odemwingie was adjudged to have pushed Nemanja Vidic and Puel was upset to see his striker penalised.
He added: "The defender is beaten, he's touched a bit and plays for the foul.
"We played a great second half and shook up this great team. We had the better chances.
"I'm proud of my players. They showed we're not here by chance."
