Romelu Lukaku has thanked Chelsea for instilling a winning mentality in him following his record-breaking move to Everton.
The 21-year-old joined the Toffees yesterday for £25m having spent last season on loan at Goodison Park.
And although Lukaku said he did not speak with Chelsea boss Jose Mourinho about the move but thanked the London club for giving him the chance to play in the Premier League.
He said: “Things happen in football and sometimes it is not meant to be.
"Chelsea are a big club and sometimes it is difficult for young players to come through.
“But they gave me the opportunity to come to England.
“Chelsea are a big club and taught me how to be professional. When I came to England I was 18 and knew nothing about being professional.
“I was very ambitious but Chelsea taught me about a work ethics and winning mentality.
“I don't have negative feelings about that football club.
“But I want to have a good career. Because in football sometimes a career is only 10 years and I didn't want to spend 10 years on the bench.
The Belgian international has signed a five-year deal believed to worth in the region of £75,000 a week.
He added: “The board and my agent did very good stuff.
“Chelsea worked with us as well and they did very good stuff to get me here as quickly as possible.
“I can have a bit of pre-season here now.
"I'm 21 it's time to have a stable career as well. It was important to be somewhere like this.
“Now I don't have doubts at the end of a season.”
