Brighton are determined not to lose highly rated centre-back Ben White for a low fee this summer.
The Premier League side are aware that interest in White is only increasing as he earns a call up to the England squad for Euro 2020.
According to the Daily Mail, Brighton will fend off interest from fellow top flight clubs by setting a £50 million price for White's transfer.
The 23-year-old will not be allowed to leave unless a club offers an astronomical sum, which the club would see as too good to turn down.
Manchester United, Arsenal, Liverpool and Leeds United are among teams who have been linked to White in the past few months.
