Bruce was resigned to losing Grealish on the cheap before Nassef Sawiris and Wes Edens' takeover last month which saved Villa from possible administration.
"We all know what football is, but at the moment Spurs haven't got anywhere near what the owners want to consider".
British media reports have linked the highly-rated Grealish with a £20-million switch to Tottenham, who have yet to make a signing in the close season. "The one thing the owners have made pretty clear is that no one is for sale", said Bruce. The playmaker could bid farewell to his beloved West Midlands club as he is now odds-on to leave before the transfer window slams shut on Thursday, with Tottenham firm favourites to sign him.More news: First Official Gameplay Trailer For Red Dead Redemption 2 Has Dropped

The club must still comply with Financial Fair Play and selling Grealish would virtually solve the issue but Bruce has told Spurs they can no longer agree a knockdown price. We all want good players, but you also need Wanyama's or whoever else you want to play in there.
The 22-year-old has an eye on a place in Gareth Southgate's England squad with the 2020 European Championships in mind, and he will have noticed how home-grown midfield talents like Eric Dier, Harry Winks and Dele Alli have earned global recognition after flourishing under Mauricio Pochettino at Spurs.
"The story has come out because we've taken a player from a certain agent".
Villa must find around £40million to adhere to FFP regulations but Bruce said they would find a way to resolve it if they did not sell Grealish, who could still play in Monday's Sky Bet Championship opener at Hull.
