Villa have issued a hands-off warning to any Premier League clubs considering a summer swoop for Jack Grealish.
Stoke City, Tottenham and Everton are all thought to be keeping tabs on the 20-year-old attacking midfielder, after he finished a difficult campaign on a high by helping England Under-21s to victory in the Toulon tournament.
Villa, who will play in the Championship next season, insist Grealish is not for sale but are likely to face a fight to keep a player who could be offered an instant return to the top flight.
The academy product made just 16 appearances as the claret and blues were relegated from the Premier League and was at one point sent to train with the club's under-21s by then manager Remi Garde, after being photographed on a night out just hours after a 4-0 defeat at Everton.
Tony Xia, the club's prospective new owner, is meanwhile expected in the UK in the coming days as he looks to complete a £75million takeover.
The Beijing-based businessman must be interviewed in person by officials from the Premier League and Football League before his buy-out of Randy Lerner can be rubber-stamped.
Roberto Di Matteo is Xia's preferred candidate to become the club's new manager. The former Albion boss's appointment should also be confirmed in the coming days.
