Chelsea are set to bring an eighth goalkeeper to the club after agreeing a £17m fee with Genk for Mike Penders.
The 19-year-old will sign a long-term deal at Stamford Bridge and is then expected to go back on loan to the Belgian club for the upcoming season.
Last month Chelsea signed Filip Jorgensen from Villarreal for £20.7m and have seven keepers listed in their first-team squad including last season’s number one Robert Sanchez and Kepa Arrizabalaga, who is back after a year on loan at Real Madrid.
Penders made his senior debut in July, becoming the third-youngest goalkeeper to play in the Belgian Pro League.
The 6ft 7in Belgium Under-19 player will become Chelsea’s 10th summer signing and will take spending beyond £150m – with Atletico Madrid striker Samu Omorodion expected to join imminently for a £34.5m.
