The 19-year old Belgian striker has been impressing at The Hawthorns on loan from Chelsea and admits he has not entertained the thought of heading back to Stamford Bridge after Roberto Di Matteo was replaced by Rafael Benitez.
"I don't think about the option," Lukaku told Express & Star. "I am very happy to be here for one year.
"After January, I am sure I will be at West Brom. I am very happy to know that in my head. Hopefully, I will do well for the rest of the season.
"I don't think things will change (under Benitez). I think he has his plans and I am happy with the team here.
"If I focus too much on Chelsea it wouldn't be good for me, so I will focus on being here. In my head, I am here for a year and it has to be clear I am here for a year and not for six months."
