Conte signed Morata to Juventus in 2014 before leaving the job a month later to take up the Italy national team job.

He left Los Angeles on Wednesday where he was training with his Real Madrid teammates. He was filmed saying his farewell to the players and officials of the club.
“Many thanks for everything. It's been incredible to once again win trophies here. I hope, whenever they're not up against my team, that Madrid always win,” Morata told Real Madrid website.
Morata will sign a five-year contract with Chelsea worth £155,000 a week. According to Daily Mail, the final figure of the deal is around £70.6m making Morata the most expensive Chelsea signing.
