Yaya Toure says Manchester City manager Pep Guardiola will demand an improvement from his players next season.
City failed to win a trophy in 2016-17 -- the Spaniard's first campaign with the club, finishing 15 points behind Premier League champions Chelsea.
Toure, who has signed a new one-year deal which commits him to an eighth season with the club, says Guardiola expects more.
He told Sky Sports News: "You can see it in his eyes -- he is not happy at all in himself.
"Next year, for sure, he is going to try to challenge for everything as much as possible.
