Brighton boss Graham Potter is chasing Genk winger Leandro Trossard.
The Mirror says Brighton are looking to sign Belgium winger Trossard in a club-record deal.
The 24-year-old scored 22 goals and notched 11 assists for Belgian champions Genk last year.
He's previously been linked with Arsenal and Everton.
But Brighton are preparing a second bid of £18m to make him Potter's first signing.
