Sheffield United are fighting to keep hold of Jack O'Connell.
The Argus says the Blades will resist any Brighton attempt to snap up a prized asset.
The Seagulls are interested in Blades defender O'Connell, who is rated at around £6 million.
O'Connell is likely to be one of a handful of defenders, including Liam Moore at Reading, being eyed by Albion as they bid to complete their Premier League squad.
Chris Hughton is keen to add a fourth centre-back to compete with Shane Duffy, Lewis Dunk and Leon Balogun.
