Lukaku struck twice in victory over Sunderland.
He said: "I want to end this season in a European spot and I know we have the players at West Brom to achieve that goal.
"We have the staff, the experience and the up and coming players to do it. We've got experienced players back now to push on in the remainder of the season."
"I have personal ambitions I want to reach. I want to score goals but also win as much as possible. If I do better and help the team, that's perfect.
"I work on all different aspects of my game and have the qualities to become the complete striker.
"I have the people around me and players around me to help me improve. Every year, every season is an opportunity to get better."
