The 21-year-old sealed his £28million move to Goodison Park this week, after Chelsea decided to let him leave on a permanent deal - returning to the club where he excelled on loan last season.
And Lukaku admits the chance to work with Roberto Martinez was a huge lure for him.
“For me it’s easy. I just want to improve and get better year after year," he said.
“I’m not saying Chelsea are not a good team but I needed to be in a place where it felt right.
“It almost feels that I belong here. That’s why I came back. I have a very good relationship with the players and the staff.
“Roberto Martinez has been very influential. He’s someone who knows football. Someone I can develop under as a player.
“He makes us all better as a team. I want to become one of the best and he wants to make our team one of the best teams in England.”
@Sterry, because Chelsea do not play with 11 kids please don't think Chelsea do not develop young players. Last season you could have had near on two teams of young talent, they go on loan or play in the reserves, Jose promotes them when he sees fit. Lukaku would be in the 1st team this season but apparently he doesn't want the competition. I could list these young players for you but frankly I can't be arsed go to the official CFCS website and look for loan players.- crow
