Brighton are keen to keep hold of Baleba, who is under contract until 2028 with the option of a further 12 months, and warned United it would take a fee around the £115 million ($156 million) Chelsea paid to sign Moisés Caicedo two years ago to get a deal for Baleba over the line.

Brighton are already preparing a Carlos Baleba replacement amid Manchester United interest in the Cameroonian.
