But the 20-year-old is only keen to stay if Everton secure a place in the Champions League.
The Chelsea striker is currently on loan at Everton from Chelsea.
“It’s a bit strange at the moment, the last time I heard from them was a couple of months ago,” said Lukaku.
“It was not the fact I was not wanted. Imagine I was playing for Chelsea now I would play maybe five games, maybe score one or two goals. But now everyone in England is talking about me.
“I want to help Everton. I admire his (Martinez’s) style, everything at the club, and I thought that was the next stage I needed for this year.
“I think we can challenge all those clubs in the top six.
“I think it’s not a bad idea (to stay at Everton for a second season). If we play Champions League then I think so.
“I miss European football a lot. I have to work hard and see what will be the best decision for me at the end of the season.”
