Chelsea have made their move to sign Tosin Adarabioyo, who will become a free agent at the end of next month ahead of summer transfer window.
Newcastle United were previously the favorites to sign Adarabioyo, but now face strong competition from Chelsea.
Manchester United have also been linked with the defender, but they have not submitted an offer.
Tosin Adarabioyo made 22 appearances for Fulham this season, scoring twice. He has spent the last four seasons with the club, setting his mark as a key player in their defense.
He has been with Fulham for four seasons and is now considering his next move.
