However, the United boss did feel that the goalless first half had a lot to do with referee Rob Styles' decision to turn down what he thought were two good appeals for penalties.
"I thought there were too many individuals in the first half trying to walk the ball into the net," Fergie said after the game at Old Trafford.
"I stressed that passing was the key element. Once we increased the tempo of the passing and movement they were a fantastic team in the second half.
"You always want a quick start to the second half and the quick goals settled everyone and after that we played some great football.
And on the peanlty decision's, Ferguson added: "I just don't understand Rob.
"He turned a penalty down in the Fulham game and there's another example today.
"I think he may be trying to make a point, 'I didn't give it last time and I'm not giving it this time'. "It's unfortunate because I think it was unfair."
