Chelsea will reportedly table a bid for Brighton & Hove Albion goalkeeper David Stockdale if they fail to secure the services of Celtic's Craig Gordon.
The Blues have identified the Seagulls stopper as potential back-up to Thibaut Courtois, according to The Mirror.
Antonio Conte's side are in the market for a new reserve goalkeeper as Asmir Begovic is expected to leave Stamford Bridge in search of first-team football.
Gordon is said to be Chelsea's preferred option, but Conte is reportedly exploring alternatives while the Scot's release from Celtic is being negotiated.
Stockdale, who joined Brighton from Fulham, has six months remaining on his current contract.
