"We won trophies with Jose and I want to thank him for that," said Pogba, who was omitted for Mourinho's last three Premier League games as United boss.

"He makes me improve, as a person as well and that's it.

"We work even if not everything went well. But that is the past and I went to thank him for that."

United produced their most free-flowing performance of the season to post their biggest win.

Marcus Rashford, Ander Herrera, Anthony Martial and Jesse Lingard (two) were on target as United scored five for the first time since Sir Alex Ferguson's final game as manager – a 5-5 draw at West Brom in May 2013.

"We are happy that the first game of the manager starts like this," Pogba said. "It's important now to carry on like that.

"We can not play like this and win with five goals and then the next game lose."

Solskjaer, who has made a temporary switch from Norwegian club Molde, has been put in charge until the end of the season when it is expected United will appoint a more experienced manager.

Sixth-placed United are eight points adrift of the Champions League places, but Pogba remains defiant over the club's long-term ambitions.

"We want to go back to the top of the league," he said.

"I'm sure that is the same of all the players and now we are looking forward to the next game.

"We are really happy for the result. We played well and the performance of the team was great."
