Mourinho's relationship with Pogba has attracted as much attention as his dealings with executive vice-chairman Ed Woodward in recent months, but events at Old Trafford appeared to be restorative.
The United boss had been braced for the deadline-day disappointment and warned ahead of Friday's Premier League opener against Leicester that the lack of improvement could return to haunt them this winter. His transfer frustrations dominate the United Kingdom football press this morning and there are rumours of discontent between the Portuguese boss and the Old Trafford board.
And he again talked about United's failure to spend on new players after adding Fred, Diogo Dalot, and backup goalkeeper Lee Grant earlier in the summer window.
"It was tough for Harry Maguire, he gave his best and had a good game".
It was the first game back with United for Pogba after his World Cup-winning exploits, and he said it was challenge to find his form before eventually giving way to substitute Marouane Fellaini in the 84th minute. "I have the foundations to do that here with the manager and my team-mates at Manchester United".
Mourinho got it right.
That was down to the organisation and discipline of the senior players that Mourinho could call upon, and how hard they worked together as a unit when they did not have the ball.

A handout photo made available by Taos County Sheriff's Office shows the booking photo of Siraj Wahhaj issued on Aug. 05 2018. Police described the compound as a small underground trailer covered by plastic, with no running water or electricity.
The Daily Mail reports that Mourinho was left "furious, angry and frustrated" after yesterday's failed transfers.
Jose Mourinho named Pogba as captain for the match, while Romelu Lukaku started on the bench for Manchester United as did Jamie Vardy for Leicester. He said: "I have my players, I like my players, I like to work with my players". I don't think he's helping the cause and he's the one who has to get these deals over the line.
'But every time he played, he did a great job and showed something great. "We have to wait until the end of November to understand if we can fight for the title". "It depends on the music, but words for me don't come easy".
"I think Mr [Richard] Scudamore must be happy because it's a good way to start the Premier League".
"Martial didn't have a pre-season", said Mourinho, quoted by ESPN.
And Pogba had the hosts in front from a penalty kick before three minutes, burying his attempt from the spot after a slow run up following a Daniel Amartey handball in the box.
