Grealish was linked with a move away from Villa Park last summer, with Manchester United considered to be the favourites to sign the 25-year-old. However, a move did not take place, and the English attacker put pen to paper on a new five-year contract at the club.
His stock has only risen since, and his impressive performances for Aston Villa this season also earned him his first call-up to the England national team.
The Independent also reveal they have been told Guardiola has also discussed Grealish's quality with Manchester City's star midfielder Kevin de Bruyne. They add the Belgian midfielder was effusive in his praises of the England star, describing him as a player the club must try and sign.
However, Man City will need to spend a huge amount to price him away from Aston Villa. The English online newspaper also note that it is understood that the new deal Grealish signed with Villa last summer involves an agreement that he cannot leave the club for a fee that is less than £100m. It remains to be seen if City will be willing to splash such a staggering amount for The Claret and Blue stars.
