Luke Shaw put United 2-0 up late in the second-half with his first career goal, before Jamie Vardy ensured a nervy finish by pulling one back for Leicester in added time. "He worked amazingly well Monday, Tuesday, Wednesday, and he's one of the players that I have to speak to see how, physically and mentally, he feels", the tactician said.
Pogba's focus on trust seemed pointed, as did his post on Twitter shortly after the match. Alexis Sanchez was desperate to take the spot-kick but captain Paul Pogba eventually slotted away in the third minute after the longest run up in history.
"Pogba was a monster", said Mourinho.
While some people suggested that Pogba's message was aimed at Jose Mourinho, a man he has a strained relationship with, others have suggested it might be because he wasn't allowed to join Barcelona or Juventus this summer.
'[I'm] very pleased, very pleased.
'With a great manager and great team-mates around me I think I've got the foundations to do that here at Manchester United'. Paul Pogba and the players that participated in the World Cup tournament will also miss but the boss would rather have them on the bench than the youngsters.
Jérôme Boateng’s agent to meet PSG on Thursday
There are reports that there are negotiations going on behind the scenes between Boateng's management and PSG. Pundits say Boateng is interested in joining PSG and has rejected an offer made by Manchester United.
Mourinho told Sky Sports on the tough decisions he faced when making substitutions: "A match where I needed six changes not three".
Pogba has been strongly linked with a move to Barcelona in recent weeks, amid suggestions that he was disappointed by Mourinho's faint praise of his achievement as he played a pivotal role in helping France win the World Cup in Russian Federation this summer.
Pogba only returned to training four days ago from an extended holiday after France won the World Cup in Russian Federation in July.
Having failed to land the new centre-back that he craved, Mourinho says that he is now in a hard position.
Pogba scored the first league goal of the season from the spot after only three minutes following an inexplicable handball by Daniel Amartey inside the Foxes' box.
"We know the players, and myself as well, didn't have a lot of training and we played a game".
Of Pogba's penalty, which came after just 75 seconds, he said: "A very good penalty taker".
