Benjamin Mendy will succeed at Manchester City, according to Yaya Toure.

The left-back became the world's most expensive defender when he signed for City on Sunday and Toure says his qualities will be accentuated in England's physical league.

However, the Ivorian has warned the 22-year old that City does not have time for him to be a slow learner.

"I know Mendy, because he's French and he's been playing for my former club Monaco. I think he's a fantastic player," Toure told Sky Sports News.

"You will see in the Premier League how powerful he is, how much energy he has. This guy is very exciting to see.

"I hope he's going to be fine in the Premier League, because it is such a tough league, and we all know you need to adapt for a month or so, or some players go on straight away.

"We will see. I hope he can adapt as much as possible because we don't have time."
