Riyad Mahrez admits moving from Leicester City to Manchester City was a culture shock.
Now in his second season with City, the winger admits he cannot relax in the day-to-day workings inside the club.
Mahrez told France Football: "The dressing room of a big club is another reality. You have to fight non-stop. Relaxing is not tolerated. I'm going to look for things more, because if you do not do it, you know very well that someone else will play instead of you.
"To make a good match, it is not enough any more, it is necessary to make very, very good matches all the time. That's Manchester City."
