The 25 year-old playmaker has been heavily linked with a blockbuster £100 million move to the Etihad Stadium in the coming days, with an official bid submitted by Manchester City on Friday afternoon.
The expectation is that Aston Villa would accept the bid, and that Jack Grealish would put pen to paper on a five-year contract with the Premier League champions, taking home in excess of £200,000-a-week.
However, while reports surrounding a move have intensified over the past few days, the Aston Villa captain has been spotted reporting for duty on Sunday - less than 24 hours after returning from his summer holiday.
Two images have emerged on social media on Sunday afternoon, the first highlighting Jack Grealish stood with Tyrone Mings - both of whom had extended summer holidays following their European Championship exploits.
The second image provides a clearer look at Jack Grealish sporting the new Aston Villa training gear upon returning to Dean Smith's side this weekend.
Despite the photographs of Jack Grealish returning to Aston Villa training, the feeling in various quarters is that the player will complete a Premier League record breaking transfer to Manchester City in the coming days.
City have a contract ready for the player, while Aston Villa remain expected to accept the staggering £100 million offer that was submitted by Etihad Stadium chiefs in recent days.
