Manchester United manager David Moyes has insisted that he will not underestimate Real Sociedad when his side face the La Liga outfit tomorrow night.

United head into the game on the back of a seven-match unbeaten streak and have won each of their last four games, a run that began with a 1-0 victory over Sociedad in the reverse fixture a fortnight ago.

A win would all but send United through to the knockout rounds with two games to spare, but Moyes insists that they will have to be at their best if they are to take maximum points from the contest.

"I certainly won't take anything for granted. I have a lot of respect for Sociedad, and we will have to play well on Tuesday if we are going to get those 10 points which will get us over the line," Moyes told PA.

"But we have got ourselves in a good position in the group and we have to try to maintain that."

United have amassed seven points from their opening three group games, while Sociedad are bottom of the group having yet to pick up a single point.
