The agent of Everton striker Romelu Lukaku has confirmed that his client's new deal at the club is "99.9%" completed.

The 23-year-old is set to become the club's highest-paid player of all time with a contract that will see him earn £100,000 a week.

However, agent Mino Raiola refused to rule out the possibility of the Belgian leaving the Toffees next summer, with some of Europe's top clubs rumoured to be tracking the striker.

"With Everton, we have 99.9% reached terms. We are talking to the club in a good spirit so we are very hopeful. There are no problems on the way that I foresee. I don't see any big problems. It is a question of putting the details on the paper. If Romelu is good enough, strong enough, to move in the next year then we will talk to Everton about it," he told talkSPORT.

"It is a very good relationship at the moment. We know what both parties want. Everton is going through a transition from a club that was maybe aiming for Europa League and now they are more ambitious and maybe in the near future will go into the Champions League or maybe even win the Premier League at a certain stage. In football, you can't look too much in front. You need to take it one transfer window at a time.

"For now, we are agreeing terms and then we will see in the summer what happens and how the situation is. If there is an interest from both parties to move on, then we will talk with the club, but at this point we only have one objective and that is to perform as well as possible for Everton."

Lukaku has scored nine goals in 16 Premier League appearances for Everton this season.
