Albion's reigning player of the season Liam Bridcutt has handed in a transfer request.
The Seagulls have refused to comment but an Argus source has confirmed Bridcutt handed in a request today.
The influential midfielder is desperate to link up again with his former manager Gus Poyet at Premier League strugglers Sunderland.
The Black Cats made a £2 million offer for Bridcutt at the beginning of the January transfer window.
Bridcutt has now made clear his wish for a move to the Stadium of Light.
He was one of the last players off the pitch and dwelt to applaud supporters chanting his name at the end of his last appearance for Albion in the 1-1 home draw against Bournemouth on New Year's Day.
Bridcutt was one of eight players left out of the side for Saturday's FA Cup win against Reading at The Amex.
