Manchester City boss Pep Guardiola admits Jack Grealish isn't getting game due to form.

And the manager has warned the midfielder faces a major challenge to get back into the starting XI.

“If Jack and Jeremy play, Phil doesn't play and Julian doesn't play. It is what it is," Guardiola told City's website.

“We need it. Now it's better. We have Oscar Bobb who has, for example, had an amazing impact and in the last game he didn't play.

“It's important because it's 90 minutes, 95 minutes, 97 minutes every game and we have players who can change from the bench, who can make the rhythm.

“Remember when Kevin [De Bruyne] came back, he was on the bench and he came in and helped us to win the game.

“With many games it's going to happen. Everyone is going to play.

“Jack is doing steps to get to his best level. Now he's competing with the players who are playing at a high, high level and that is the only reason why.

“He has to get back to what he was especially last season and all the period at Villa. I am looking forward to giving him minutes.

“This season was not like last season but he's getting better. That's what we're looking for.

“Always I'm pleased with all my players and Jack as well.

“It's not a big, big problem. Completely the opposite. Now he's making steps to get to his best and that's all.

“We need him and need everyone. We need Jack. I am looking forward to have him back to his best and give him minutes."
