Yes, only club that currently exists for Lukaku is Al Hilal which plays in the Saudi League. Although Lukaku doesn't want to play other than League Serie A, but it seems he will play in Saudi, also Chelsea has reportedly given the green light to Al Hilal. Actually Inter have been trying to be able to recruit again, but Lukaku has another agreement behind Inter, if Lukaku not had another agreement maybe he ready at Inter right now, because the club has already received money from transfer fee andre Onana.
Yes, Inter have finally abandoned any negotiations with Lukaku and now they are trying to negotiate with Folarina Balogun from Arsenal. The striker spent last season on loan at Reims, but now Arsenal are planning to sell their striker for at least 30 million euros. This is more expensive than Inter planned to spend on Lukaku, but they will probably go for it, as they consider Folarin to be a more promising striker. I think Lukaku will have other options and Saudi Arabia will not be his only choice.
