Romelu Lukaku is confident he will have no problem replacing Zlatan Ibrahimovic as Manchester United's striker.
But he acknowledges he will have to work far harder than he did at Everton.
Despite a stunning scoring record at Goodison Park, there have been questions about the Belgium international's work rate after he completed a medical ahead of a £75 million move.
Lukaku has already attracted the wrong sort of headlines when he was arrested in Los Angeles over the weekend, after police were called to a party at the mansion he had rented while on holiday in the city.
But Lukaku is determined to prove he is worth the money that has been spent.
"Who would say no to the biggest club in the world," said Lukaku. "This is an opportunity that I've wanted since I was a child. Now it's time to work harder than I ever did before.
"Zlatan did a wonderful job," Lukaku told ESPN . "He was the main guy at Manchester United, and a guy I really look up to.
"But I'm Romelu Lukaku - not Zlatan Ibrahimovic. I will fill up the striker position in my way, but I know I have to work really hard and deliver more than I've done before."
