Man City boss Guardiola's warning to Jack Grealish.

Jack Grealish joined Man City for a British record £100million from Aston Villa in the summer and Guardiola is keen to see more from him this season.

Pep Guardiola insists that England international Jack Grealish must hit form this season for Manchester City or else 'he will be in trouble'.

Grealish, who sealed a move from Aston Villa to Man City in the summer for a British record fee of £100million, has come under scrutiny as many are keen to see him flourish at the Etihad like he did at Villa Park.

Since he signed for the Cityzens, Grealish has scored two goals and registered three assists in 15 appearances for the club.

The 26-year-old missed City's last three games due to injury, but is back training and could feature in City’s away clash against Steven Gerrard's Villa on Wednesday evening.

“He’ll be in trouble [if so] - we want to see it now,” this was Guardiola’s response when quizzed if it would take until next season for Grealish to hit top form.

Callum Hudson-Odoi - ‘It was a disappointing one for us’ against Man Utd.

“We’ve six or seven months left, with a lot of nice things, we want to see it this season.

“I would say he’s settled perfectly, he knows many English players, and the other guys are nice people.

“He’s not a problem, he plays good, but has to find a bit of time, if you analyse the games, he’s not played bad.

“With the quality he has, it’s difficult to play badly. Playing every three days, its different for him, but he did it incredibly well.

“What he did at Villa was amazing, helping them get up and stay there. Now, in the international break, he came back injured, but he’ll come back step by step and we’ll see his form.”
