Ferguson - after the Champions League: W. Rooney was fantastic © EuroFootball.com

Former Manchester United manager Sir Alex Ferguson praised forward Wayne Rooney for showing good athletic form and stated that the key to success is the healthy Nemanja Vidic.

"Wayne was fantastic. I was pleased to see that," said the Scot about the match against Bayer. "His energy, determination, desire to attack returned. As a director, I am very happy that he was back to what we remember."

Ferguson continued: "What is important and the key to this team is for Vidic to stay healthy. With Van Persie and Rooney, we have forwards who can win matches.

Valencia has returned to his best form and it's strange how a jersey number can change a player. De Gea is maturing, Evra was usual, and Carrick continues his form from last season. There were many positive things."
