Manchester City eased to a 2-0 win away to Arsenal on Sunday to begin their Premier League defence in classy fashion.Lots of last season's heroes, from Nicolas Otamendi and Kevin de Bruyne to David Silva and Leroy Sane didn't start, but Benjamin Mendy did.It's safe to say that the left-back has endured an extremely eventful time since joining City from Monaco for £52 million - a then-world-record fee for a defender.Mendy only featured eight times last term after rupturing his anterior cruciate knee ligament yet still ended up being a part of France's World Cup winning squad.Following Arsenal 0-2 Man City, Pep Guardiola revealed he isn't happy with some of Mendy's habits, and the Frenchman has already reacted.

Mendy loves a bit of social media

Whilst Mendy recovered from surgery and a season-ending injury, the left-back regularly posted humourous, light-hearted messages on social media.

So, despite a lack of game time, the 24-year-old became somewhat of a cult hero amongst Man City fans, who loved seeing him show off his human side.

Guardiola speaks about Mendy's social media habits

Mendy looked pretty solid defensively at the Emirates Stadium and, going forward, he assisted both Raheem Sterling and Bernardo Silva's goals.

However, his manager Guardiola has now admitted that he isn't happy with how active his full-back is when it comes to social media (mainly Twitter).

Speaking about Mendy's performance in his post-match press conference, 47-year-old Pep said: "Mendy is Mendy.

“Sometimes we (Man City coaching staff) want to kill him and sometimes you think 'Wow, what a (good) player we have'. He gives us energy.

The Spaniard continued: “Mendy has a lot of things to improve and hopefully we can convince him to forget a little bit the social media and improve a few things.”

Mendy reacts to Pep's criticism

So, Guardiola is hoping that Mendy focuses less on his tweets moving forward, and ironically, it was on Twitter that the player delivered his reaction.

First, the popular Mendy spoke about City's fine start to the new season and thanked their travelling supporters.

Then, shortly afterwards, he saw Guardiola's criticism of his social media habits and described how he felt with two tweets, which you can see below.

That "Oops" certainly suggests Mendy will take his manager's words to heart, and next up for the champions is the visit of Huddersfield Town on Sunday.
