Sir Alex Ferguson was in ebullient mood after watching his team destroy Wigan 4-0 and storm to the top of the Premier League.
Second half strikes from Carlos Tevez, Wayne Rooney and a brace from Cristiano Ronaldo saw the Red Devils gain their sixth successive league victory.
Wigan came to Old Trafford intent on defence and stifled United until the 54th minute when a well-taken Tevez goal opened the floodgates.
The glut of goals made a change from 1-0 victories United have been grinding out and, when asked what pleased him most, the goals or going top, Ferguson told Sky Sports: "Going top, but you had to win to get to the top.
"I thought it was our best goal-scoring performance of the season.
"Considering all the things that happened - Louis Saha injured in the warm-up, then John O'Shea coming off, Vidic coming off, I think we have done fantastically well."
He said United played "some fantastic football in the second-half" and thought the depth of his squad contributed to the victory.
"If we're going to win something, the squad is going to do it. We had 10 players missing - we ended up with 10 players out so it is a great credit to all the players who played," he said, adding the flow of United's play was much better in the second-half.
"I think we speeded the game up in the second-half. I think the first half with all the things that happened we tried to get some sort of a consistency and a performance whereas the second-half the flow of our game was much better."
Ferguson was also happy to see Tevez and Rooney continue to develop their striking partnership.
He said: "It was excellent. They are coming together, there is an understanding obviously that comes about with that and I think we saw some of it."
Ferguson added that Vidic had been taken to hospital with concussion while O'Shea was suffering from a dead-leg, and Saha felt his knee in the warm-up and they "couldn't risk that".
Asked how significant the day was, he said: "It is a long way to go. I think what is significant is I am very confident with the squad I have here. I think they have shown that. I am really proud of some of them who have come in."
