The Spain international is yet to agree terms with the Premier League champions but is set to replace the departing Diego Costa at Stamford Bridge.
Chelsea have agreed a deal to sign Real Madrid striker Alvaro Morata, the club have announced.
Reports suggest the Premier League champions will pay £70 million for the Spain international, who is yet to agree personal terms or undergo a medical.
Manchester United had previously held an interest in the forward, but instead opted for Romelu Lukaku.
Morata will arrive at Stamford Bridge and will be tasked with replacing Diego Costa, who is set to join Atletico Madrid after being told he is surplus to requirement by Antonio Conte.
He will become the Blues’s fourth signing of the summer, with Willy Caballero, Antonio Rudiger and Tiemoue Bakayoko already secured.
The 24-year-old leaves Santiago Bernabeu just a year after returning to the Spanish capital from Juventus.
He scored 20 goals in all competitions for Zinedine Zidane’s side, but struggled to hold down a regular starting berth with Karim Benzema and Cristiano Ronaldo acting as competition.
Morata has made 21 appearances for Spain, scoring nine goals in the process.
