Brighton are in talks with Derby County over a proposed £10million deal for right-back Jayden Bogle.
Bogle enjoyed an outstanding breakthrough season at Derby under Frank Lampard's tutelage as the Rams just missed out on promotion.
The defender does not turn 19 until next month but has already made 50 first-team appearances.
Brighton are also keen on Portsmouth defender Matt Clarke and Girona forward Portu, says the Daily Mail.
However, Portu is expected to sign with Real Sociedad.
