Pogba said: "He is just a happy person. He just smiles every time, and he brings smiles to people.
"I had the chance to be with him a few times in the reserves.
"So I have known him for a long time and have a very good relationship with him.
"Even once when I was at Juventus, we saw each other.
"He is a very nice guy, a very good person.
"He has been very nice with the players and very close to the players.
"The first thing he said when he came in was, 'Enjoy playing football'.
"That is the only thing he said to us, and that's what we did and what we do.
"The last months were not the best, and when you don't win games, you don't enjoy. It was tough.
"But we had injured players as well, and I think that had an impact on results.
"We are still learning, still growing and trying to come back to the top
"We want to play in the Champions League, win the Premier League - that is the goal of the club.
"So that's what we try to do, and that's why Ole came back."
