HITC Sport understands from sources close to the club that Fulham have made a bid for Brighton defender Lewis Dunk.
Fulham boss Kit Symons has made a new central defender one of his top targets this summer and has already made a bid for Wolverhampton Wanderers stopper Richard Stearman.
Symons is also an admirer of Dunk and is understood to have tabled a £2 million offer for the 23-year-old as he looks to bring him to Craven Cottage.
Derby County have also been credited with an interest, but Fulham are hoping to steal a march on their rivals by tabling a firm offer for the centre-half.
Brighton are keen to keep hold of one of their prize assets, with Dunk only signing a new four-year deal last summer.
Dunk, who has come through the ranks at Brighton, is regarded as one of the best young defenders outside the Premier League after catching the eye at the Amex Stadium.
Dunk has made more than 100 appearances for the Seagulls and was a virtual ever-present last term making 44 appearances and scoring seven goals.
