Lukaku got his goal, which helps him to quickly get back to normal and nobody cares whether he scored that against 9 Napoli players or 11 Napoli players. But for Napoli the tendency for the moment is bad and stopping it is hard.
Even though Roma's current performance is not consistent enough, I am sure they can get a place in the UCL next season by finishing in the top 4 of the standings.
It is not impossible of course as they are very close to the top 4, but I am hesitant to believe they will make it eventually. The top 4 are set in stone almost I would say although maybe AC Milan will get into deeper trouble over time. But then there is some unexpected competition from Bologna and Fiorentina and Napoli is still not out of the game for the top 4. It is a single point separating them from Roma. If I had to pick my top 4 right now, I would not choose Roma.
At the moment the problems Roma face are also still the same namely in the attack which is sometimes not too erratic which makes this more complicated for themselves.
Indeed, Lukaku's presence adds some positives because even though this still cannot be compared to prime Lukaku when at Inter but he has been able to provide slightly better results because the 14 matches he played in Serie A he has scored 8 goals and 5 goals from 6 Roma matches in the Europa League in my opinion it is a good achievement.
If Mou can maintain this then indeed their big chance for the Champions League or more certainly the Europa League will be very there its just that we also cannot fully believe that this can be done easily for Roma in their current condition.
