I think so too and the peak of Lukaku's career has passed in the previous few seasons, although Lukaku is still in good form and still able to score goals for the next few seasons. Another consideration is age that is no longer young and other factors due to frequent injuries.

For the next season Lukaku can still contribute to Inter Milan, even though his goal statistics are not as good as in previous seasons. Lukaku also has an advantage in aerial balls and his header will be a threat to opponents, but the problem is that Inter Milan cannot fully rely on him alone because if he gets injured it will affect Inter Milan. So the option of buying another striker must also be considered because after all Inter Milan will play in many competitions next season.
