QPR's midfield maverick was reunited with Redknapp last month, two years after being shown the door by him at Tottenham.
The Morocco star, 23, said: "Every time you come back for a new season, it's a new start.
"I don't have a problem with Harry. Even when he wasn't here as manager, I was in touch with him.
"We get on so he'd call and say 'Congratulations, I'm proud of you'. So it was good to see him walk through the door here.
"People forget that when I was at Tottenham I was only 17 and I had players in front of me like Luka Modric and Rafa van der Vaart who are top players.
"The first man who sent me to QPR was Harry because he told me I needed games. When I came here, I loved it and had a great time.
"Afterwards, I went back and Tottenham were about to qualify for the Champions League so I knew it'd be difficult to get in the team.
"So I went to see Harry and told him I wanted to leave but he told me 'No, I won't let you go'.
"But after that he saw that I really wanted to go to further my career.
"Now we're back together and it's a good chance for me. I have to do my best and the manager will make his choice. I respect that."
