According to The Express, Villa want as much as £40 million in order to part company with the 22-year-old, who can operate as a winger or an attacking midfielder.
Grealish is a hugely talented and promising young attacking player who scored three goals and provided six assists in 22 Championship starts for Villa this past season.
Former Tottenham manager Tim Sherwood worked with Grealish at Villa, and he rates the young attacker very highly.
The Mirror quoted Sherwood as saying about Grealish in September 2015 when asked how much he was worth: “I wouldn’t want to sell Jack Grealish for £60million today put it that way. I know what he could possibly be.
“What looks expensive this year might not be expensive next year. That’s the way the game is going.
“He’s a great player is Jack, but he’s got to realise – I’ve been on at him every day – there is more to the game than just when you’re in possession.”
