They signed Kepa Arrizabalaga from Athletic Bilbao within a couple of hours of agreeing terms with Madrid for Courtois.
Then it was announced that 23-year-old Kepa had penned a seven-year contract with Chelsea making him the most expensive goalkeeper in history at 80 million euros ($92 million).
The 27-year-old now has two years left on his contract with the Blues and earlier this summer, his comments indicated that he was considering a move away from the west London club.
Eden Hazard has hinted he is keen to leave Chelsea this summer as he eyes up a move to Real Madrid, but Blues officials have told Yahoo Sport that they will not entertain any offers for their number 10.
Personal terms will now be discussed and if true, Kepa will be in London tomorrow for a medical and so on.
Kepa has emerged as Chelsea's preferred choice to replace Thibaut Courtois, who declined to report for training at their Cobham training ground on Monday as he attempts to force a £35m transfer to Real Madrid.
Real, meanwhile, confirmed Courtois will undergo a medical on Thursday morning before signing a six-year deal.
His future has always been speculated amid Madrid's pursuit of Manchester United keeper David de Gea, however, the veteran has played a key role in the capital.
He helped the Blues win two Premier League titles, one FA Cup and one League Cup during his time at Stamford Bridge.
Kepa, on the other hand, has been at Athletic Bilbao for just two seasons after moving from Real Valladolid in 2015.
