Rooney has been used on the flanks in recent weeks due to a lengthy injury list at Old Trafford.
The England striker featured on the wing against Marseille on Wednesday and he was satisfied with the draw in France.
“We’ve got a lot of injuries at the minute, so I don’t have a problem [playing on the wing],” Rooney told Uefa’s official website.
“It was quite a difficult game for us. Marseille didn’t cause us many problems, but we didn’t create as many chances as we’d have liked.
“We had a few big players missing and I think they would have made a difference had they been here. The fact we didn’t lose is very positive.
“We’ve got Marseille at home now and we know that if we beat them we’re through to the next round. We’re confident at home and we have to be positive.”
