Solskjaer, who had only just returned from two years out with a series of knee problems, was forced off in the last minute of the match in Denmark and is likely to miss United's forthcoming matches against Portsmouth, Southend, Blackburn and Sheffield United.

United boss Sir Alex Ferguson admitted he was relieved the injury was not more serious and said: "It's unfortunate for Ole. It is a hamstring and he will be out for a few weeks. But I am actually quite happy.

"Given his previous history of knee problems, I was a bit concerned when he came off but, fortunately, it is only a hamstring."
