According to Sky Sports News, the 22-year-old has only recently emerged as a target for Spurs, but they've made a significant move for the youngster before a number of Premier League rivals.
Chelsea, Fulham and Leicester City are also credited with an interest in Grealish, who excelled for the Midlands outfit in the Championship in 2017-18.
"Villa value their prize asset at closer to double that figure—and they could be more interested in a bid from Chelsea, especially as it is likely to see Grealish loaned back to the club for next season," the report continued.
