The United boss pointed out that his back four had a great game and reserved particular praise for them.
"I felt eventually we were the better side," said Fergie.
"Credit to the players at the back who did a great job. "We rode our luck a bit but on the counter attack I thought we could have scored more goals."
Welbeck also received praise, he added: "In the last few weeks he's really come into his game, he's got over the bad injury he had last season and he's getting better all the time."
