Grealish, 25, is due in Manchester to sign his massive contract ahead of finalising the British record transfer deal, per Daily Mail.
Man City have kept tabs on the England international for some time now, having opened talks last week and offering his £100 million clause last Friday.
It appears Pep Guardiola will get his man this summer despite Aston Villa's best efforts.
The Midlands club tabled a huge new contract, reportedly offering their captain a £200,000-a-week deal.
Grealish, who returned to training on Monday, seems set to complete his transfer to Man City ahead of the new season.
Dean Smith's side had hoped to hold onto their prized asset and build a team around him for the upcoming campaign.
They've been busy this window, signing Emi Buendía and Leon Bailey while eyeing the likes of Tammy Abraham and James Ward-Prowse.
Man City, meanwhile, still remain interested in signing Harry Kane who failed to attend Tottenham training.
Another big transfer could be on deck to lure Kane to the Etihad.
Will Grealish and Kane be teammates at Man City? Watch this space.
