Mourinho surprised many fans and pundits by starting the French World Cup victor when many felt he would be left out having not completed a proper pre-season.
"We've learnt from the past that, if he takes too many players on like he did at Chelsea and Real Madrid, then there's only one thing that will happen".
The World Cup victor seemed to restore the faith put in him by Mourinho with his performance on the night, with a penalty in the 2-1 win the icing on the cake for the midfielder, who left the field to a standing ovation in the 84th minute. For us it will be a hard season because I had my plans, and I had my plans for many months, and I started the Premier League season without a situation I thought.
"Every team is a good team, forget the name, forget the history, forget the shirt".
"That's football, that's football management, I think football is changing and probably football managers should be called head coaches".
"We have to wait for end of November, beginning of December to understand how things are going and if we can fight for the title". The Reds will be desperate to be closer to neighbours Manchester City this season, after Pep Guardiola's team finished 19 points ahead of the Reds last term.
The France star was named skipper for his side's 2-1 victory over Leicester City on Friday and delivered a commanding performance, which included a goal from the penalty spot.
Mourinho is believed to have clashed with United's hierarchy over the profile of transfer targets, with the likes of Toby Alderweireld, Jerome Boateng and Diego Godin considered too old by the board.
In comments widely regarded as reflecting continuing problems with his relationship with the United boss, he wrote: "I'll always give my best for the fans and my team mates, no matter what's going on".
It was far from an incendiary message but in mentioning colleagues and supporters the omission of his own boss appeared a stark one.
"Very good players, fantastic investment, an awesome squad".
"We thought maximum 60 minutes but he managed (more than) 80".
