Bebe set up the winner for Shinji Kagawa.
Ferguson told manutd.com: "I think we had plenty of possession of the ball and Kagawa was involved in most of that. He was man of the match and he deserved that. He took his goal quite well, although it was a deflection. It was good work by Bebe too, who set it up for him. I think Bebe did really well when he came on.
"Kagawa has settled in well. He's going to be a really good player and he impressed tonight. His awareness of receiving the ball, his speed in turning and how he attacks defenders is an asset to us."
