The 20-year-old Belgium international, on a season-long loan from Chelsea, came off the bench to score the winner in the Toffees' 3-2 Premier League victory at West Ham on Saturday.
Lukaku scored 17 goals while at West Brom in 2012-13 and says that he tries to absorb as much as possible about the movements and techniques of fellow strikers and opposition defenders.

"I take my time to study and to learn other strikers' movements and to learn about other defenders. I take my time.
"Really I want to be one of the best in this league so you can only learn from the best by watching the best. After training I go home and record every game. I have a satellite and I just watch the games."
It serves his ultimate goal of becoming one of the best players that the world has ever seen, with his loan spell all about taking his game to the next level.
"My aim is to go down as one of the greatest," Lukaku added. "That's why I'm at Everton. I'm here to help the team, the team is here to help me.
"Everton were that step I needed. As a team they are always close to the top four and get to cup finals. That was really interesting for me."
