It was a good result and a good team performance, Ferguson told Sky Sports.
"We had to show a lot of discipline, but in terms of playing football we were the better team,"
"It is about winning the game and certainly the moments when we did play football in the first half we were the better team.
"I said before the game that the games between the top sides were going to be important this year and that was an important win for us.
"I've always said about December if we get to New Year's Day and if we can be top or just about there then we have an outstanding chance of retaining the title."
