Manchester United boss Jose Mourinho says Wayne Rooney's needs a settled role to return to his best.
He says a constant shift in positions has not helped his skipper.
Mourinho said: "I think it then created a bit of a doubt in relation to his role, to his position, to his future and I think players especially in moments of less confidence, they need to be clear in his head.
"He cannot be jumping from No 6 to No 9, or No 9 to No 10, or No 9 to No 6. For me, he is an attacking player. What is an attacking player for me? For him, a 9 or 10.
"Play No 6, play in midfield, not with me unless we need it and unless we ask him to do that, but with me, I want the ideas completely clear. He is a second striker, plays behind the striker or as a striker. That's what I think is Wayne Rooney."
