Ribery says United are nothing without Wayne Rooney.
Ribery, who, along with Arjen Robben, is "carrying the banner" for Bayern in the opinion of Sir Alex Ferguson, said in The Sun: "Rooney is carrying the United team this season. We must pay great attention to him.
"He's having a tremendous season and I am happy for him. He's a player I like a lot.
"He's hungry. He gives everything for his team. He will tackle, he defends, he attacks, he scores goals. He's full of confidence."
Ribery added: "The whole world sees us losing but I think we have a great chance. We have a team good enough to believe in."
