Albion have been linked with renewed moves for former transfer targets Adam Clayton and Joe Mason.
The Seagulls and Championship rivals Middlesbrough are reportedly in talks with Huddersfield over midfielder Clayton.
Albion had a £1 million bid for the free-scoring 25-year-old rejected during the January transfer window.
Huddersfield's signing of Radoslaw Majewski on loan from Nottingham Forest has prompted speculation they are ready to sell the versatile Clayton, who can operate in front of the back four or just behind the strike force.
Albion also had Cardiff striker Mason in their sights in January as a potential replacement for Burnley-bound Ashley Barnes.
The 23-year-old former Plymouth forward had a spell on loan at Bolton last season and Wanderers are believed to want him back.
Mason's opportunities are expected to be limited at Cardiff following the signings of Adam Le Fondre and Federico Macheda.
