Ferguson:
"Scoring four goals away from home in Europe is a great achievement. I think our attacking play was very, very good and we could have scored more.
"Early in the season we had some problems with Tevez and Nani because they had not had a pre-season with us and Rooney and Cristiano Ronaldo were injured or suspended. We did not have the ammunition then but we do now.
"Last season we made some changes which didn't work out for us in Copenhagen (when they lost 1-0), then lost to Celtic and we had to win the last game in Lille but this side are more mature now.
"But our attacking play was excellent tonight. We could have scored a lot of goals. Yes, there have been some moments when they were a bigger threat in the second half but all in all we're very happy with the result.
"They're all adapting and getting on with it and we're not worried about which formations we're playing or which players because they've all got great ability. We're happy at the moment."
About the penalty:
"Yes. The linesman seemed to have accepted it was a penalty but the referee was unsure. But it was a penalty."
More:
"We have the strength in depth; the changes are not affecting our performances.
"John O'Shea and Darren Fletcher, who we brought in, have been with us a long time and they understand what playing for the club means. They have been with Manchester United long enough to know how to adapt and here you saw how they did it."
