I heard other news that AC Milan is also interested in Lukaku. So it's going to be really interesting. But it seems that Lukaku personally is more comfortable playing at Inter Milan. I think Inter Milan should be bolder to buy Lukaku from Chelsea. Because AC Milan might suddenly appear and intend to buy Lukaku.
this is still a mystery of rumors that there is no certainty and if you look at Lukaku's condition it looks like he still wants to stay at Inter Milan but sometimes what worries him is that Ac Milan sometimes makes big offers and this confuses Lukaku to make his choice.
but here the only one who still has power over Lukaku is Chelsea. So if Lukaku agrees to join AC Milan but Chelsea say no, I think it will be very difficult.
but let's see what will happen and I would guess that Lukaku will stay at Inter Milan.
