Rooney push significant - Robson

West Brom manager Bryan Robson suggested that a push by Wayne Rooney on Paul Robinson was a contributory factor in his side’s 3-0 defeat to Manchester United.

A moment of frustration from Rooney saw him push his man-marker, with Robinson then falling into Thomas Gaardsoe and being laid out cold. He had to go off and the full extent of the injury will be known in the next 24 hours.

"I could sense Wayne was getting a bit frustrated," said Robson. "I had watched all the tapes on United and Rooney has been running the show.

"I wanted to put him out of the game and Paul was getting a lot of joy. "Wayne pushed him in the back and it was unfortunate his head went into Thomas’ thigh.

"He was concussed but he has come round quite well in the dressing room. "We will not make any decision about him until it settles down tomorrow."

United manager Sir Alex Ferguson had this to say: "He (Rooney) will get a lot of that (man-marking), particularly in Europe, but I am sure he will learn.

"Wayne just seemed to shove the boy a bit and he ended up colliding with one of his own players.

"It was unfortunate for West Brom because I thought they were doing pretty well but the game was starting to change for us and we were starting to open them up a little bit."
