Jose Mourinho was again "very happy" with the performance of his side as they secured their second consecutive Premier League win in as many games.
The Red Devils enjoyed plenty of possession and produced a very positive performance at home to beat Southampton by 2-0.
And the Portuguese says he felt "completely at home" as he was cheered by the fans in his first Old Trafford appearance of the season.
"I'm very happy," Mourinho said.
"I know we cannot play 90 minutes the way we want to.
"It's impossible to have that consistency for 90 minutes. In many moments, for long periods in the game, we played offensively like we want to play and were very solid defensively with 10 players defending and not 6, 7 or 8. It was a collective effort so I'm pleased for the boys.
"I felt completely at home. I know I'm not a very nice guy, not smiling or waving, but it's not in my nature. Once I leave the changing room, I get into my game."
