I feel that Inter Milan will not get a second agreement to borrow Lukaku again from Chelsea. Because for now Chelsea is one of the teams that has sold more players and this option might also be exercised with Lukaku. if inter milan can't afford to buy Lukaku from Chelsea it could be that Lukaku will go to another team.
At present there is no team that has taken Lukaku from Chelsea even though there have been rumors in several media that AC Milan will be after him, but this is also still uncertain because any team will also look at the price first and if during this transfer period there is no team that If you want to buy Lukaku, you can be sure that Lukaku will return to Chelsea next season. After all, it is also very good because Chelsea is also in need of great players to improve their own performance next season.
Indeed, the Saudi Arabian team is very financially strong in recruiting star players. I think only saudi arabia team is front to get Lukaku because no other team really wants to get Lukaku in this season window. I also heard that Ac milan wants to buy Lukaku, but are they really serious.
This is just a rumor and should not be taken seriously. Because if the price is high, of course this agreement will not happen and I would also prefer Lukaku to return to Chelsea so that Chelsea's strength can increase a little. Especially with the new coach and also new players at Chelsea, of course it will really help Chelsea if Lukaku can provide even better achievements next season.
