Chelsea boss Antonio Conte is excited to be working with Alvaro Morata.
Conte is convinced the striker has much room for improvement.
"He made a good step forward since three years ago; now he is one of the best strikers in Europe," he said.
"He has great potential, he can improve a lot. Last season he didn't play a lot of games but scored 20 goals [from 19 starts]. He is very young and has a lot of space and room to improve and I want to improve him a lot."
