Lukaku recognises the importance of obtaining regular football at this stage of his career if he is to realise his goals in the game.
He said: "For me, the next two years, it is very important for me to play. I'm just 19 and even though I'll be 20 next year, people will still look at me like a baby.
"The next year I'll be 21, I'll still be a baby in some people's eyes. Then there is the World Cup with Belgium and stuff like that. I want to play as much as I can in the next two years so at 21 I can be where I want to be.
"Last year I had good preparation at Chelsea, now I can show myself at West Brom. My dream is always to play for Chelsea, so my main ambition will be Chelsea but now it's West Brom - and West Brom is on my mind.
"The club made a big effort for me to come here and hopefully I can do the business for the team."
