Valencia ace Nani is backing former teammate Wayne Rooney to recapture his best form at Manchester United.

So far this season, Rooney has one goal in seven appearances and the debate rambles on as to where his best position on the pitch is.

"Rooney is a special player. Strong, fantastic quality, shooting, vision - very intelligent," Nani told Omnisport.

"I enjoyed playing with him. He is a player who is a big part of Man United. He has chance to improve that and build his story.

'"If he continues to play at high level he can become the best there."
