That is the huge claim from former Tottenham boss Harry Redknapp.
Grealish has been linked with Tottenham all summer but with six hours left until the transfer window closes the 22-year-old looks set to remain at Villa Park.
Tottenham and Villa have not been able to reach an agreement on a fee for the midfielder.
But Redknapp thinks Tottenham chairman Daniel Levy could still pull off a deal for Grealish.
“Daniel [Levy] is a shrewd operator, don’t you worry,” Redknapp told talkSPORT.
“He’ll know what’s going on with the Jack Grealish deal, for sure.
“I think it’ll be a last minute job.”
Tottenham are yet to make any signings this transfer window despite manager Mauricio Pochettino insisting they needed more players to win trophies.
But Redknapp feels Tottenham’s bench needs strengthening, not their starting XI.
“They’re not that far short,” he said.
“If you look at Tottenham’s squad, they’ve got great cover in most positions. The only area they haven’t really got cover for is Harry Kane.
“But if you’re looking to bring a striker in, you’re basically going to tell him you’re not going to play – that’s the problem for Spurs. Even Grealish, it’s a gamble for him if he goes to Tottenham. I like him, he’s fantastic talent, but is he going to play?”
MOOTED DEALS AS THE TRANSFER DEADLINE LOOMS
France’s World Cup-winning midfielder has been subject to a concerted push from Barcelona to prise the 25-year-old away from Old Trafford. Pogba is in his second spell at United, with a stint at Juventus sandwiched in between. Tensions appear to have built between the all-action star and Red Devils boss Jose Mourinho, with Barcelona appearing ready to pounce.
Harry Maguire/Toby Alderweireld/Jerome Boateng
Manchester United’s dogged pursuit of a top-class centre back is expected to end with the capture of one of this trio. Leicester’s Harry Maguire has been a summer-long target for United, but his fine World Cup exploits with England have pushed up the Foxes’ valuation of one of their top assets. Spurs defender Alderweireld has been eyeing a move away from the north London club for some time now, and could be about to get his wish. Bayern defender Boateng has emerged as a possible fall-back option for United in the last few days.
Wily playmaker Grealish had appeared on the brink of an Aston Villa exit, with Tottenham the chief suitors. But Villa’s new owners are rumoured to be close to rebuffing the latest in a long line of attempts to prise the 22-year-old away from Birmingham.
Frankfurt midfielder Rebic lit up the World Cup as Croatia stormed to the final, leaving the 24-year-old’s services in high demand across Europe. Manchester United are rumoured to top that list of suitors, and still have time to conclude a deal to bring him to Old Trafford.
