Manchester City boss Pep Guardiola is confident of more from Jack Grealish this season.

Grealish starts his second season with Guardiola with his manager demanding - and predicting - a much-improved showing as the former Villa man aims to cement his place in England's World Cup line-up.

"The most important thing you need to know about Jack Grealish is that he won the Premier League; he came here to help us to win the Premier League and he did it," said Guardiola.

"Jack is incredibly loved in the locker room. He is so humble and people like him. Of course I want more, not just from Jack but from everyone.

"I want more, definitely I want more. And he will have to fight. We have a small squad and competition up front is so big and they are really, really good players. But it is what it is. At the end of the day everybody knows Jack. Every player.

"One minute on the field show me. The much better you play the more chance you have to play more minutes. And we are optimistic because he has arrived here well and he knows he has the World Cup around the corner.

"The manager Gareth (Southgate) knows he has a big selection because there are many good players in England national men's team. And everyone knows what they have to do."
