Lukaku is on-loan at WBA from Chelsea.
He said: "I've a manager here who is really at me all the time and wants me to improve. West Brom at this time is the perfect environment for me to play and improve to help me to be ready to play for when I go back to Chelsea.
"I don't want to be on the bench. I want to start there but I'm 19 and need to play as much as I can now."
