Alvaro Morata has insisted he is committed to Chelsea and is happy in London.
Morata was signed for £58m from Real Madrid in the summer as a direct replacement for Diego Costa, the striker who forced through a return to Atletico after never settling in three years at Stamford Bridge.
The 25-year-old Spain striker, who had a spell at Juventus, claimed comments reported in an interview with Gazetta dello Sport yesterday in which he suggested he was not content in the English capital were "a problem of understanding".
Speaking at a press conference at Stadio Olimpico ahead of tonight's Champions League tie with Roma, Morata said: "If Chelsea offered me a 10-year (contract), I would probably sign it.
"I'm very happy in this club, I'm very happy with everything in London. I really like London. And if I do well and improve, I can stay here more than five years. But I need to score many goals, otherwise Chelsea will buy another player. It's normal."
Morata was asked to clarify remarks in the Italian sports paper interview in which he described London as "stressful".
He said: "I really like London. But in future, when I need to take my children to school, when I finish my career, I prefer to go back to my country. It's normal.
"Now I'm very happy. When I say it's a stressful city, I'm talking only about the traffic. I also said it's an incredible city, with many religions and different people."
