Mourinho's men will be back in action on Sunday, when they visit struggling Burnley at Turf Moor.
"We wanted to start the season well and three wins out of three is a great start". It has been a tough place for us to come. He needs to find a way to get himself and his team out of their downward spiral, but talking about the past isn't the way do it. Three Premierships I have won, more Premierships than the other 19 managers put together.
Mourinho reminded the players they were on top at half time before their disastrous second half.
Mourinho then left his seat repeating "respect, respect, respect" as he walked out.
"Another silly, stupid goal".
"We took our chances and coming here to Old Trafford and winning 3-0 is a big, big result".

He added that Russian Federation will respond without hurting its own interests and continue a "calm and methodical work on a constructive agenda".
"And obviously to the fans that came out tonight, we're sorry, we'll be better next week". The club is working so hard and trying to deliver that as soon as possible'.
"By the tactical point of view, we didn't lose, but we lost the game". There are lot of positive things but we've got to get points.
"I don't think it's normal to lose a game at home and the supporters to react the way they did". We were not risky enough, because Sevilla deserved to win the match.
Allardyce maintained that Man United were "so good" on the night and that they outplayed Tottenham in the 90 minutes.
"Tonight, personally for me, I don't really care about my performance", Shaw said.
The result is a positive for Spurs in a season which has started with uncertainty after the opening of the new stadium was delayed and the club made no summer signings.
"We lost last season here against Sevilla (in the Champions League) and were booed because we deserved, because we were not good, because we were not unsafe enough, because Sevilla deserved to win the match, we were booed and deservedly".
