Rooney has been out of action with an ankle problem for a month, but is expected to make his return against Wigan this weekend.
Rio said: “Hopefully Wazza will come back and be the Wazza we remember. That is what everyone is hoping.
“He has gone away and worked really hard physically.
“We all hope he comes back in great shape and ready to play for Manchester United and England in the future.
“A fit Rooney is one of the best players in the world.”
