Speaking to Sport magazine in Belgium, 22-year-old striker Lukaku has admitted that he spoke to Martinez this season when played out of position for Everton.
Lukaku said: “The coach is the boss, but if I notice that something is not right, then I say something.
“I am a striker. At one point I went to the coach and I said to him: ‘With all due respect, when I'm a winger I'm hopeless. I will only score goals if you put me up front’. That was true. The games that I did not score, I was on the flank. Then I stood in the attack, and I scored.”
Lukaku enjoyed a strong season at Goodison Park, although he was far from his peak talented that were shown last season.
His debut season at Everton, having signed on a permanent transfer from Chelsea last summer, has brought a return of 20 goals in 48 games across all competitions, ending the campaign as Europa League top socrer.
For a 22-year-old that is an impressive return, and there is no doubt that he will continue to improve.
However, in the past there have been questions about his attitude and commitment, with many believing his move from Chelsea was due to frustration having not been starting striker during any of his time at Stamford Bridge.
His latest comments prove that he has no trouble disagreeing with his manager if he feels that he is being undervalued, but it is hard to deny that Lukaku made the right decision in talking to Martinez.
He looks a forlorn figure out on the wing, and with Everton’s lack of goal threat, placing their one impressive striker further away from goal is a strange move.
When returned to the central role the Belgian international went back to scoring frequently, and Martinez would be wise to keep Lukaku as his main forward if the Toffees are to have any future success.
