The Premier League champions made their first big deal of the summer after completing a club record change for the Aston Villa star
Manchester City broke the UK transfer record by completing the £ 100m ($ 139m) signing of Jack Grealish from Aston Villa.
The England international has signed a six-year deal after turning down an offer for a new contract at Villa Park.
Grealish, 25, who was given the number 10 jersey vacated by Sergio Agüero, will make his debut in the Community Shield bout against Leicester City at Wembley.
What was said
“I am incredibly happy to have come to Manchester City. City are the best team in the country with a manager who is considered the best in the world – it’s a dream to be part of this club, ”said Grealish.
“For the past 10 seasons they have consistently won big trophies. That Pep came here took them to the next level and the football this team plays is the most exciting in Europe.
“Playing for Pep and learning from him is going to be special and it’s something any top footballer would want.
Why City wanted Grealish
Along with Tottenham striker Harry Kane, Grealish has been identified as a top target for Pep Guardiola as he wants to defend the Premier League title and get even better in the Champions League after losing to Chelsea in the final last season.
City broke their own transfer record last summer when they won 62 million.
Grealish will add even more threat to the Premier League champions and can play either as a winger or an attacking midfielder.
Why did Grealish leave Villa?
Grealish, who joined Villa at the age of six, signed a new contract with Villa in September that would keep him at the club until 2025, and was given an upgraded contract to stay at Villa Park.
Villa owners Nassef Sawiris and Wes Edens have ambitious plans for the club and have invested in the squad, bringing players like Emi Buendia, Leon Bailey and Danny Ings all on board.
But the opportunity to play in the Champions League and fight for silver was too much for Grealish to turn down, while the 25-year-old undoubtedly enjoyed the chance to work under Guardiola.
