"Playing for this manager, the only person who has been able to go and do what they want in a Pep team is (Lionel) Messi, which is fair enough," said Grealish to the Manchester Evening News. "You can't knock what the manager has done, he's an incredible manager, a great guy with a really good heart as well.
"At times this season I have struggled a little bit with myself and he's been there for me all the time. I owe him a lot. He's a great person and the best manager to ever exist.
"It's been a difficult season for me personally after the highs of last year. I spoke to the manager a lot and he's been so good with me. I owe him a little bit and want to repay him now with my performances and the team as well.
"I speak to my friends in the (dressing room) everyday, I know how important I am to the team. I speak to the manager, and at the back end of last season you've seen how much the manager played me.
"I do seem to play in the big games. I saw (Karim) Benzema say it last season in an interview - everyone is so focused on goals and assists. I want to score, because in football there is no better feeling than scoring goals, but it is a team game and I am so happy to keep playing for this team."
