Mourinho's broken relationship with Pogba was thought to be a factor behind his December dismissal, but the playmaker told a press conference his old boss was shown the door because of poor results, per Goal:
He said: "What were the issues? We were not winning. That's why they decided to change the head coach. The results matter the most. If we were winning, we would have good results and the coach would have remained at his position. That's all."
Ole Gunnar Solskjaer was appointed Mourinho's replacement on an interim basis. Results have improved drastically since his arrival, and the Norwegian is expected to be named his permanent successor, per the Guardian's Jamie Jackson.
United went unbeaten in their first 11 games under Solskjaer, having suffered a 3-1 defeat to Liverpool in Mourinho's last game in charge. The team won six of their last 18 games with the Portuguese at the helm.
Pogba's performances in particular have improved. Sportswriter Kris Voakes recently noted his return to a leadership position in the squad, having been stripped of the vice-captaincy when Mourinho was boss in September:
The Frenchman racked up three goals and three assists in his first 14 Premier League appearances of the season under Mourinho. He's scored eight goals and recorded six assists in his 13 league appearances since Solskjaer took over.
The Red Devils suffered just one defeat in their first 17 matches under Mourinho's replacement but have now lost back-to-back games and were knocked out of the FA Cup by Wolverhampton Wanderers on Saturday.
That 2-1 defeat at Molineux served as a reminder United are still far from being an elite side, per Goal's Sacha Pisani:
A 2-0 defeat at Arsenal prior to that left United outside the Premier League's top four, with their UEFA Champions League qualification hopes now hanging in the balance.
Pogba isn't the only player at Old Trafford whose displays have improved following Solskjaer's appointment, and one could argue striker Marcus Rashford has benefited even more so:
United return to Premier League action after the international break when they host Watford on Saturday, March 30.
