Having Lukaku back in the team and in the shape he is currently in is never bad of course, but the really decisive scenes in this game were the red cards. Those cards pulled the rug under Napoli's feet.
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.
Roma will try to get into the top 4 of the Serie A standings. This will help them get Lukaku permanently, which is said to be one of the conditions for Roma if they want to get Lukaku permanently. It's still quite confusing why not let Lukaku go permanently if Chelsea doesn't really need his services.
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.
If you are talking about good clubs for the 4th spot, exclude Roma. I do not have that serious conviction about Roma, that club's second name is disappointment. It is when you hail them more that they will disappoint you the more, so I do not have serious trust in them. Mourinho has tried in these years to turn the table around but he couldn't, and at the 6th position, I believe they have gotten the fair share of their performances this season, and I don't think they can get higher than that at the end of this season. There are clubs like Atalanta, Napoli and Lazio that are still serious threats to the current standing of Roma, I hope that in the next 2 weeks, they will not be displaced even lower contrary to the belief you guys have about them.
They just don't have that feat yet. As for AC Milan, one should know that they are trying, at the top 3, they have done so well, although it's because many clubs in the Serie A are not so impressive, yet, they deserve the current standing. However, they had it tough in their last match with Salernitana, it was good luck that saved them, or else, Salernitana would have won that match eventually. I hope they can try better in the coming ones and they should be able to beat Sassuolo FC easily with my analysis. Nonetheless, concerning Bologna and Fiorentina, they are doing well and they should continue to do well. But concerning Napoli, I must say I do not have any hope in them again, the gaps are too wide, and not even Victor Osimhen can do anything again unless for a miracle.
