Crystal Palace are finalising the £22.5m transfer of Adam Wharton from Blackburn after he underwent his medical on Wednesday.
The deal is worth £18.5m plus £4m in add-ons for the 19-year-old who is signing a five and a half year contract at Selhurst Park in a significant move for the club.
Championship outfit Blackburn want to keep Wharton on loan, but the player is willing to leave now with Palace struggling in the Premier League.
Wharton, who has been at Ewood Park since the age of six, signed a deal in December which would have kept him at Blackburn until the end of the 2027-28 season.
