Morata has hit the ground running for Chelsea since his summer arrival.
He told the Daily Mail: “Zidane wanted me to stay and I was happy in Madrid. But I couldn’t stay to be a substitute. You reach a point that you need to play, to grow up, to escape a comfort zone. It’s about being comfortable. I don’t want that. I am ambitious and hungry to succeed.
“For Spain, the more I play, the more goals I score, the more chance I have of making the World Cup and starting games.”
