Brighton and Hove Albion Chief Executive Paul Barber has reiterated the club have no intention to sell Ben White this summer.
Leeds United have already seen two bids knocked back, with the highest at £22million.
According to Sky Sports, Leeds United have made a third bid for Ben White, believed to be in the region of £25million, although that appears to have also been rejected.
With the new season less than three weeks away, Leeds may be forced to turn their attentions elsewhere, with Freiburg defender Robin Koch understood to be on their list of alternative signings.
As far as the Whites' pursuit of White goes, Brighton have handed yet another 'hands-off' warning to Leeds or any other suitors, with Manchester United and Liverpool also linked.
“He is a terrific young player," Barber told talkSPORT.
“The whole point of him going out on loan was to develop him in League Two, League One, the Championship.
“Leeds did a fantastic job in helping us develop him. But we are looking forward to Ben playing for us in the Premier League and certainly, that’s what he will be doing.
“We haven’t got any interest in selling Ben.
“He is training with the squad and we are looking forward to seeing him in action in blue and white stripes very soon.”
Brighton are stocked with centre-back options although they have allowed Matt Clarke to rejoin Derby County on loan, whilst Shane Duffy has been linked with a move away.
