If we check statistics in Serie A actually Lukaku did not contribute much to Inter from 25 matches Lukaku scored 10 goals and 6 assists but in the Champions League a little better 8 matches 3 goals overall not too impressive. Lukaku's best career in 2020/2021 when he got several awards after moving to Chelsea his career seemed dim and now he is 30 years old so I thought he only had 3 years to maintain his career, besides the Saudi League and Inter who else wants to approach Lukaku? I have never heard of another club want to bring Lukaku.
Romelu Lukaku career was ruined after his departure from Inter to Chelsea where he couldn't do anything. Chelsea spent a lot on him and got nothing in return and they have to give him back to Inter. They try to get like €40m from Inter which is trying to spend €30m after getting money from selling 2 players.
Inzaghi wants Lukaku back and the player denied an offer from Saudi Arabia Al Hilal so I assume it is a matter of time to see Lukaku back in Inter, at worst as a loan.
