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.

Carlos Baleba's Brighton future is up in the air and Man United are pushing hard to agree landmark deal very soon

The Manchester Evening News reported on Friday that United were unlikely to complete a deal for Baleba before the transfer window shuts on Monday, September 1. It's understood that Brighton will want at least £100m for the Cameroonian as they look to repeat the business that saw Moises Caicedo leave them for Chelsea.
