The Everton star reveals how he has transformed himself from bright young talent to one of Europe's leading strikers.
Everton striker Romelu Lukaku has told the club's website that only by studying his own past performances and comparing them with top players has he been able to kick on and become one of the most lethal strikers in Europe.
The Belgian is enjoying the most successful season of his career, and netted his 24th and 25th goals of the season in all competitions in the FA Cup quarter-final against former club Chelsea.
With around two months of the campaign still to play, he has already scored five more goals in 12 fewer games than he did last term, with his tally of 20 from 2014-15 previously standing as the joint-highest total of his career.
Previously a top talent at Anderlecht and a revelation whilst on loan at West Bromwich Albion from Chelsea, the 22-year-old has now developed into one of the most consistently-dangerous strikers around, with ex-Toffees striker Daniel Amokachi comparing him to former Ballon d'Or winner George Weah.
He told the club's website that it is only his hard work on and off the training pitch which has helped him improve year on year to reach the standard he is at today.
Lukaku said: “Work ethic is the most important thing. You already have your natural ability, nobody can take that away from you. But without the work I have put in, I wouldn’t be able to do what I’m doing today. I would be the same player as I was before, who was maybe a bit rusty with his touch, not able to hold the ball up and offside too much.
"I analyse my own game for at least two or three hours every day. I think it’s important to be constantly busy with your game. If I want to improve on a daily basis, which I need to do and I feel like I am doing, then I need to know what my mistakes are and where my attributes are up to.
"Football, for me, is not a job - it’s my passion and the thing I love the most. I come home, I rest, eat and then when I wake up from a nap I will take my computer and watch many different players. You can always get better. You can be the most talented person in the world, but you need to work hard to unlock it."
Lukaku is likely to be a man in demand this summer after his fine season, with former Everton and Manchester United striker Louis Saha urging the Red Devils earlier this month to bring the Belgian to Old Trafford no matter what the cost.
However, Lukaku himself insisted after the win over Chelsea that he is not thinking about a potential move away from the club, and his focus does indeed seem to be purely on improving his game even further.
He will be hoping to continue his fine run of form, which has seen him score five goals in his last four matches, when his side host faltering Arsenal this weekend.
