Mahrez IS a bit of an asshole.
I could give you tons of examples but I'll give you one that happenned just last week :
Gueye kills Gundogan ankle and everyone goes towards the ref. Mahrez sprints and vehemently barks at Gueye.
Gueye answers : I know I made a foul it's OK, I know I did. Mahrez continues to bark and asks the ref for a red card, that he saw it all, etc... Bakker comes in and says "you can't have seen anything from where you were". Mahrez looks at him and says "who the f*** is this guy anyway? Does he even have a name?".
That's obviously not a big deal, but a good way of seeing Mahrez' character. At Bakker's age, he couldn't break Le Havre's first XI in Ligue 2. Bakker was starting a CL semi final (and he totally stifled him in fact).
He's not a very respectful guy.
Kante is arguably the nicest guy in football.
To be fair I’ve never heard of that Bakker dude before the semis either, can’t blame Mahrez on that one
And a lot of players and FO people at City love him, just ask Bernardo, Mendy, Sterling, Gundo, Jesus, Bergueristain, Zinchenko, Cancelo, Stones, Dias
Kante and Mahrez are good friends too, they stayed on the pitch chatting forc10 minutes after the last City Chelsea game
