Courtois expected in Madrid on Thursday

Chelsea are finally prepared to let the Belgian leave the club after activating the release clause in Athletic Bilbao goalkeeper Kepa Arrizabalaga's contract.

Athletic have already announced that the 23-year-old will be leaving the club, thus allowing the goalkeeping transfer merry-go-round to begin.

According to the aforementioned source, Courtois will arrive in Madrid on Thursday to complete a medical and complete the formalities of the deal.

Terms are already thought to have been agreed between both clubs and with the player. Courtois is expected to sign a five-year deal in the Spanish capital, with Chelsea making €35m from the deal.

Interestingly, former Real Madrid target Kepa has proved key to the deal, despite snubbing Madrid's interest earlier this year by signing a new long-term contract with the Basque outfit.
