Real Madrid is expected to pay Chelsea £35 million pounds for Thibaut Courtois and the deal includes Mateo Kovacic joining Chelsea on a season-long loan.
Chelsea have already moved to replace Courtois, activating the €80 million (£71.5m) buyout clause in the contract of Athletic Bilbao goalkeeper Kepa Arrizabalaga to make him the world’s most expensive goalkeeper.
In 2014 he returned to Chelsea and won two Premier League titles in four years with Chelsea, as well as the League Cup in 2015 and FA Cup in 2018.
