Fergie told Sky Sports: “We made a lot of good chances, we played really good football, we played with speed.
“It was difficult for a couple of players who were playing their first games. It was a big ask for them to complete 90 minutes.
“Maybe in the second half it opened up because a few players were starting to feel it.
“I have no complaints. On another day we could have scored four or five.
“They are a very experienced side, very competitive team. They defend determinedly.”
Fergie added on Ronaldo’s comeback: “He has had a turbulent summer and a lot has been said about it but when I had my meeting in June in Portugal with him that was over.
“He dedicated himself to getting fit and his commitment to the club.
“It (the crowd’s reception) was important for Cristiano.
“I think he realises what a great club he is at and how loyal the fans are. He will take great encouragement from that.”
