Manchester City manager Pep Guardiola is known for his no-nonsense approach to the game but a recent interview with player Samir Nasri has shed new light on one of his more controversial rules.
Guardiola has banned his players from having sex after midnight, even if they are off the next day.
Speaking to French newspaper L'Equipe, Nasri said it was one of the first rules set by Guardiola after his arrival at City. The midfielder is currently on loan from City to Sevilla.
Nasri said Guardiola's policy is there to get to best out of his players.
“He told us this is how he managed to get the best out of [Lionel] Messi and [Robert] Lewandowski, and for them to avoid the maximum number of muscular injuries", Nasri said.
He went to commend Guardiola's unprecedented attention to detail.
“With Guardiola, on the first day of training, you know how you should play, how to squeeze and also how to stand off the ball,” he said. “The next day, you have videos for everything that you have to do.
“He will not bully you, but he will do everything to make you progress, to get you to know you how to position yourself and how to play. He's a picky person.”
Nasri admitted to the newspaper that he had been scrutinised by Guardiola for returning to pre-season training "a little out of shape".
“Guardiola told me that I was a mess, he told me several times and even kicked me in the butt, literally.
“When I returned from holiday having had a year with injury problems and personal life problems, I was a little out of shape. Not as much as what was said but a few, four kilos overweight. For Guardiola, over 2.5 kilos and you do not you train with the group.
“Guardiola told me with your qualities you should not be at Manchester City, you should be at Barcelona. We had some discussions, he wanted me to stay and play for him. I told him no, because he couldn’t assure me a first team place, I wanted to play. He told me he thought I was making a mistake, but I still have a two year contract."
