Alvaro Morata has passed a medical ahead of his move to Chelsea from Real Madrid, according to Sky sources.
Morata is expected to join Antonio Conte's squad in Singapore this weekend as they continue their preparations for the new Premier League season.
The 24-year-old exclusively told Sky Sports News on Thursday that he was joining the "best club" after Chelsea had agreed an initial £58m deal with Madrid for his services.
"This is the best club," Morata told Sky Sports News reporter Paul Gilmour upon arrival in London.
"Antonio Conte is one of the best coaches in the world and I'm so happy to work with Antonio."
Morata, who only re-joined Madrid from Juventus last summer, scored 20 goals in 43 appearances last season as Zinedine Zidane's side claimed a La Liga and Champions League double.
He will become Conte's fourth major summer signing following the arrivals of Willy Caballero, Antonio Rudiger and Tiemoue Bakayoko.
Conte has been keen to strengthen his attacking options having told Diego Costa he is surplus to requirements at Stamford Bridge and missed out on a deal to sign Romelu Lukaku to Manchester United.
Costa, who scored 20 goals last season as Chelsea won the Premier League title, is yet to secure a move away the club and has been excused from their pre-season tour of Singapore.
Sky Sports News understands Atletico Madrid are interested in re-signing Costa and are expected to make an offer for him.
Atletico are currently under a transfer embargo and would be unable to register Costa as their player until January.
