Boss Sir Alex Ferguson revealed that he is planning to bring some experienced heads into the starting eleven, but he is giving nothing away just yet.
"I have not picked my team yet," he said.
"We are coming into a period where we have the Benfica game, then Chelsea on Sunday, Leeds United on Tuesday, then Stoke away on the following Saturday. Obviously the squad will be used but first of all we are giving a lot of consideration to Benfica.
"I have not decided [who will play]. I have a few things to think about. But it wouldn't worry me at all to play the [same] team that is doing well."
