Morata sought to clear up doubts in an interview given to the Italian press.
He said: “I want to say that we had a problem of understanding in this interview. If Chelsea proposed me 10 years I’d probably sign that too.
“I’m happy with this club, in this city, with everything in London. I really like London and, probably, if I make good and improve, probably I can stay here more than five years. But I need to score many goals otherwise Chelsea will buy another player. It’s normal.
“I want to say, probably in the future when I finish in my career, I won’t live in London. But now, at the moment, I’m very happy in London and enjoy living in London with my wife.
“Probably in the future, when I need to bring my child to the school and take up a school, when I finish my career, I’d prefer to come back to my country. It’s normal. For me, I prefer the place I was born.
“But now I’m very happy. When I say it’s a stressful city, I’m only talking about the traffic and that there are a lot of people. But it’s an incredible city with many religions and many kinds of different people, so I really enjoy London.”
