Lukaku, 24, continues to be linked with a move away from Everton, with Chelsea, Manchester United, Bayern Munich and Juventus all reportedly interested in signing him this summer.

The Belgium international, who stalled on signing a new Everton deal in March and has still yet to commit his future to the club, says a decision on his future has already been made.

"My agent knows what's going to happen," Lukaku told Sky Sports. "I know what I want to do, and whenever something happens, you guys will know."

Speaking to reporters in Belgium while on international duty, Lukaku added: "I know what's happening. But I can't tell you anything more. I know what's happening, but I will leave the talks to my agent.

"The most important thing is I want to win trophies. We are now talking to the club. As for the rest, I'm looking ahead. What I would like most is to play is in the Champions League and try to win the Premier League once. Or better, a few times. That would be the most beautiful thing.

"That's important for my progress as a player. I don't want to stay at the same level. I want to improve and I know where I want to do that."

Asked if he could be talking about United, given his agent Mino Raiola's previous dealings with the club, Lukaku said: "I'm the player, I will take the decisions."
