Ronaldo says he needs time to regain full fitness, following his summer ankle operation.
He said: “It will be another two or three weeks before I can give 100 per cent.
“I feel very good. There is good improvement there and I am very happy to be back.
“But my ankle has still not fully recovered. I still feel it a little bit.
“The medical staff say that is normal and I feel very confident about the future.”
He added on Dimitar Berbatov’s goals against Aalborg last night: “It’s good for Berba to score his first goals for United and he played well.
“It’s always good for forwards to score, it keeps your confidence high. Everyone knows he’s a good player.
“His style is different to Carlos Tevez and Wayne Rooney but after two or three games we’re getting better together.
“He’s a fantastic player and he’s going to help the team a lot.”
