Chelsea signed goalkeeper Robert Sanchez from Brighton and Hove Albion on a seven-year contract on Saturday.
The transfer fee was reported to be 25 million pounds (USD 32 million) for the Spain international, who is expected to challenge Kepa Arrizabalaga for a starting spot.
The 25-year-old Sanchez made 23 Premier League appearances last season. He joined Brighton as a teenager and progressed through the club's academy, becoming the Seagulls' first-choice goalkeeper during the 2020-21 season.
Chelsea, which hosts Liverpool on August 13 in its season opener, has made seven summer signings under new manager Mauricio Pochettino.
