But in football terms, his education is largely complete. At the age of only 16, Anderlecht striker Lukaku finished the 2009-10 Belgian campaign as the league's top scorer with 15 strikes from 33 appearances, despite often being utilised as a substitute. His impact also extended to the Europa League, where, in December 2009, he became the third youngest goalscorer in European club competition when netting against Ajax at the age of 16 years and 218 days.
Lukaku replicated his form in the 2010-11 season and continued to be linked with a move away from Anderlecht. Jose Mourinho admitted he wanted to bring the striker to Real Madrid while the teenager was pictured wearing a Chelsea shirt during a tour of Stamford Bridge - sparking speculation that West London could be his destination.
Finally, in August 2011, Lukaku agreed a deal in the region of £20 million to join the Blues and new boss Andre Villas-Boas hailed him as a ''very exciting young talent''.
Strengths: An imposing physical specimen, Lukaku is strong, tall and quick, and possesses the positional awareness and quality of finishing to mark him out as a superb all-round striker. He is also a focused and determined character.
Weaknesses: Few, though there is a concern that sitting on the Chelsea bench will stunt his development a touch. He may benefit from developing a more rounded game, rather than being honed as a lone striker.
Career high: Finishing the 2009-10 Belgian season as the league's top scorer, despite still attending school.
Career low: Missing out on a place in the 2010-11 Champions League when Anderlecht were defeated by Partizan Belgrade in a penalty shoot-out in the play-offs.
Style: Dominant, explosive, prolific. A potential phenomenon.
Quotes: "I don't like people talking to me about the Champions League. It wasn't me but my team that won. Chelsea really wanted me last summer and paid a lot for me but, after a while, I thought, 'Are you just throwing money around?'" Romelu Lukaku, May 2012
Trivia: Romelu Lukaku's father, Roger, was a professional footballer in Belgium.
