I think it'll be very difficult for Romelu Lukaku to join another Italian club this season and that's because of how much he loves Inter Milan and his continuous desire to play the Milan club.
Since his services are no longer needed at Chelsea I think it'll be a good decision for Lukaku to go to Saudi Arabia. Age is no longer in the side of the powerful striker who knows how to bully defenders with his strength and tactics. Saudi Arabia clubs will offer him the best financial package he can get from anywhere at the moment
If Romelu Lukaku still loves Inter Milan so much, of course he will find a way to leave Chelsea and not instead accept an offer from the Saudi Arabian club at this time. But if Romelu Lukaku prefers to think about money, it is clear he will accept a very lucrative offer from the Saudi Arabian club rather than stay at Inter Milan or Chelsea. Especially now that he is no longer young, so he must be able to make wise decisions for himself before next season starts.
As far as I know Lukaku has rejected offers from the Saudi League so he changed his mind? somehow I'm not sure Lukaku is comfortable there because the customs and culture are different maybe this is the reason why he doesn't want to move to the Saudi league , not because he doesn't need the money

Inter Milan have reportedly abandoned their plans to sign Lukaku the reason is because Lukaku communicates with Juventus, obviously Inter Milan don't like it because Juventus is one of their competitors next season so the news of Lukaku's transfer to Inter is closed.
Lukaku seems to be moving to Juventus almost definitively. He turned down Milan because of their poor performance in the Champions League. In general, he is a strange guy, after all, given the fact that his career is not in the best condition could go to the Saudi league and continue his career in peace, because while scoring Lukaku has not yet learned and just in the Saudi league could show his potential.
