At the end Lukaku will be in Serie A.
Mourino have convinced him to come to AS Roma.
It will be another Chelsea loan and a very good opportunity for AS Roma.
Maybe Mourinho knows how to treat Lukaku for the AS Roma team in an attacking position, because AS Roma itself is also lacking players in the attacking position so that also fueled Mourinho's conviction to sign Lukaku from Chelsea after Lukaku had an uncomfortable moment recently with the Chelsea coach. So it is a very good opportunity for AS Roma if they are able to get Lukaku this season with any status.
This could be a good option for AS Roma if Mauricio Pochettino still doesn't include Lukaku in his project this season. Moreover, Mourinho really likes a striker with a posture like Lukaku, and definitely reminds Mou of Drogba before at Chelsea. If you look at the AS Roma transfer market, there have been no significant surprises so far, Lukaku arrival could be a new recruitment for the capital team.
Even if Lukaku is willing to go to SPL, he will get a high fee there. But I think the reason he didn't leave was to secure his place in the Belgium squad, he could lose that if he went to the SPL.
I think Lukaku can be a good option for AS Roma because at the moment Roma is being hit by a striker crisis due to Tamy Abraham and Dybala struggling with injuries. Apart from that, the Roma management, which is known to be very economical in spending money on spending on players, is also another reason and borrowing the Chelsea striker will be an advantage for both parties. And I'm sure Lukaku can get back to what he's capable of under Mourinho and the two of them will understand each other's characteristics
