Chelsea are keen to secure Brighton loanee Levi Colwill to a new deal.
The London Evening News says Chelsea wants to renew his contract which expires in 2025.
There are growing fears, however, that Brighton could again test Chelsea's resolve by trying to sign Colwill permanently this summer after initially trying to poach him during the 62million sale of Marc Cucurella to Stamford Bridge.
The centre-back, a graduate of the Cobham academy, joined the Seagulls on a season-long loan in August - when current Blues boss Graham Potter was still in charge at Amex Stadium.
Colwill has impressed under Potter's successor Roberto De Zerbi, with seventh-placed Brighton enjoying a fantastic Premier League campaign to still harbour genuine hopes of European qualification with 13 games still to play this term.
However, his progress on the south coast has been disrupted by injury, with the 20-year-old having recently missed several games with a quad issue sustained in January.
