The Chelsea striker had the option of moving back to West Bromwich Albion, where he spent a hugely-successful campaign last season.
However, on deadline day Lukaku opted for Everton ahead of a return to The Hawthorns - and he insists he is happy with his decision.
"I am very glad," he said on Sky Sports News. "I read that some said I was not happy but I am very happy - this is a club that can bring me a lot, and I can bring a lot too.
"I still hope to grow and bring a lot to this team."
Lukaku says that he left Chelsea on good terms, as a number of people were shocked by their decision to loan him out.
"I think at my age it is important to play a lot, I have a good relationship with the coach at Chelsea and I hope to have good results," he added.
