Everton striker Romelu Lukaku has made it clear he's made a definitive decision over their new contract offer.

Lukaku turned down a new and improved offer from Everton 10 days ago worth £140,000-a-week.

Chelsea and Manchester United have both been linked with moves for the striker since then, with the Blues already having a bid rejected to re-sign him last summer.

"The decision has already been made so I can't talk about that," Lukaku said.

"There is nothing wrong with ambition. You have to embrace it and where you are as a footballer.

"I've made a long way until now but the road is still long and I know I have to improve and get better.

"I want to help Everton as much as I can, as well as the national team. I think a lot of stuff can be achieved.

"Sometimes people will mistake things that I say but it's just ambition that I have; I want to win titles and trophies and I don't think people should take that as arrogance - people should embrace it.

"This is what footballers need to achieve if they want to become the best, and I think young kids need to learn that too."
