The Algerian winger, who bagged the opening two goals in the 6-1 victory at Aston Villa, says the City striker is one of the greatest he has ever played with.
"We try to pass to each other and try to give each other more chances to score - and that's what this team is all about," said Mahrez.
"The stats speak for themselves. He's a legend for the club and Premier League.
"He shows it every week and I'm very happy to have him in the team.
"He has a lot of quality but he doesn't need a lot of chances to score, so that shows how big a striker he is."
