United won the game 3-0 at Old Trafford.
“I was pleased. It was a controlled performance and we showed a lot of patience, particularly in the first half when you try to open them up,” he told ESPN. “Fortunately we got the goal at the right time.
“The second goal put us in the comfort zone and from then on I didn’t think we could possibly lose it.”
Fergie also commented on their race against Chelsea for the Premier League title.
He added: “If we get to New Year within a point, or a point ahead, or level, or roundabout the top of the league, we’ve a big chance in the second half of the season.”
