Aalborg boss Allan Kuhn has asked the UEFA to review the video of an incident involving Manchester United hero Wayne Rooney.
Kuhn has said that he was not certain that it was intentional but some of his assistants was convinced the England striker deliberately landed on Kasper Risgard.
"I think he did it but I am not 100% sure, so I can't go after him," Kuhn said.
"I was not sure during the game and I have not seen the pictures, so I cannot be 100% sure. But some of my people have seen it and said it was.
"It is not good for a fantastic footballer. You have to keep your head and stay calm in situations like that, especially when you are a world-class player.
"But that man was a little bit frustrated today.
"Stupid things happen in football but the Champions League people will take care of it if they have seen something on video. I am not worried about it."
