Mourinho was fired in December after a 3-1 defeat to Liverpool.
However, his failure to get the best out of World Cup winner Pogba, was often cited as a factor in the Red Devils’ poor form.
Interim boss, Ole Gunnar Solskjaer, has since revitalised United, with Pogba playing a starring role, scoring eight Premier League goals under the Norwegian.
“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,” Pogba told a news conference, ahead of Friday’s Euro 2020 qualifier against Moldova.
