United boss Mourinho had a frustrating transfer window, with Fred, Diogo Dalot and Lee Grant heading to Manchester.
Mourinho's relationship with executive vice-chairman Ed Woodward has become fractured, and the new plans at United would be an attempt to bridge the gap between them.
A 2-1 victory on Friday night, built around a stirring performance and an early penalty from World Cup victor Pogba as well as Luke Shaw's first career goal, might have been cause for good cheer but Mourinho chose the occasion to revisit his concerns over the club's recent business.
The midfielder helped Jose Mourinho's team kick off their Premier League campaign with a 2-1 win over Leicester by scoring an early penalty in Friday's game at Old Trafford, coming at the end of a week during which there has been speculation about the Frenchman's future. "For us, it will be a hard season because I had my plans for many months". I've tried to help him feel at home so he can play better and better and he feels comfortable.
"We don't have a penalty taker, it's how we feel and I chose to take it".
Sarri learns lessons from Chelsea's opening win at Huddersfield
Before the second goal, the Terriers had hit a post through Steve Mounie's header, but it was to be Sarri's and Chelsea's day. It took us a while to get going, but once we did, Huddersfield didn't stand a chance.
"Paul was fantastic, his contribution was incredible", Mourinho said after taking his captain off late in the game.
Mourinho lent heavily on those that served him well during a disrupted pre-season at Old Trafford, but such options are no slouches and it showed after 77 seconds when Shaw fed Alexis Sanchez to get away a shot handled by Daniel Amartey. I came in the academy, I grew up.
After the win, the former Juventus player said that "I always give my best for the fans, for the team mates and for the people who trust me", which appears to be a slight dig to his current manager, Mourinho often benched the £89 million player last season.
"We thought maximum 60 minutes but he managed (more than) 80".
So, could the reports of a rift between Pogba and Mourinho be true or are the midfielder's comments being blown out of proportion?
"The thinking was that he is a very good penalty taker and he likes the responsibility of it and he's the first choice", Mourinho said, via the Mirror. Lukaku then passed up a golden chance when Schmeichel spread himself well to turn the Belgian's effort over the bar.
