United fans purred at the presence of Pereira, Fred and Paul Pogba playing together in midfield and Andreas reserved some kind words for our World Cup victor, who played over an hour after less than a week of training.
But Pogba also had his say after the game, writing on Instagram: "I'll always give my best for the fans and my teammates no matter what's going on".
It was a good match with three good teams, in my opinion.
But Nicholas felt Mourinho's actions were out of character and not genuine. Leicester got off to a poor start to the season but were able to climb the table throughout the season, finishing ninth.
Jose is the type of manager who gives someone the captaincy for the right reasons and I think he made a decision to give Pogba some responsibility for managing the game and the players around him, which was a very clever move.More news: EPL: Manchester United vs Leicester City
The comments from the Portuguese and Pogba are sure to see contentment behind the scenes come under bigger focus, but Friday's win was a welcome boost at a time of apparent discontent.
There were a few nervous moments for United at the end when Vardy pulled a goal back.
"It's three points, it's what we wanted", Pogba said.
"We changed the goalkeepers with Lee because Joel [Pereira, loaned to Vitoria de Setubal] is such a good young goalkeeper that he needs to play".
He added: "The thinking is he is a very good penalty taker and likes the responsibility of it and he is first choice".More news: Man United beats Leicester 2-1 in Premier League opener
I had my plans, and I had my plans for many months, and I find myself in the beginning of the Premier League with the market closed, and I'm in a situation that I thought was not going to be the situation I would be in.
Jamie Vardy got Leicester's late reply at Old Trafford (Steven Paston/PA).
"The start to this season is so important", said Neville.
"So, it's pretty early to speak about this now", Pogba said when asked of their chances of success this term.

Mourinho's enthusiasm for Harry Maguire was not shared by the Old Trafford decision-makers and, when the club approached Leicester, they were put off by the kind of fee that would have been necessary to sign the England global in the wake of Virgil van Dijk's £75 million transfer from Southampton to Liverpool last season. "I need a reaction of some kind to show I'm really in this, I'm totally committed to it".
