Brighton goalkeeper Robert Sanchez is expected to undergo medical at Chelsea have both clubs agreed a deal worth £25m plus add-ons.
Sanchez, 25, is expected to challenge Kepa Arrizabalaga for the number one spot.
The Blues have been looking to add a goalkeeper to their squad following the sale of Edouard Mendy to Al-Ahli in Saudi Arabia.
Robert Sanchez will be familiar to the coaching staff at Chelsea as goalkeeping coach Ben Roberts worked with him while at Brighton.
The Spaniard has been with the Seagulls since the age of 15, having joined their academy from Levante in 2013.
After loan spells with Forest Green and Rochdale, Robert Sanchez made his Brighton debut in November 2020 and became the Seagulls’ first-choice stopper for the best part of two years.
He was also called up by Spain in 2021 and was part of their squad at both the delayed Euro 2020 tournament and the 2022 World Cup, although his only two caps have both come in friendlies.
Robert Sanchez lost his place to Jason Steele in the second half of Brighton’s 2022-23 Premier League season, although he did play in the FA Cup semi-final defeat on penalties by Manchester United at Wembley.
His contract at Brighton, where Sanchez has made 90 appearances in total, was set to run until June 2025.
