That is correct. It was easy to predict Napoli win, that's for sure. Things are not going so good for Roma anyway. Their rotations are too narrow. They come out with the same 11 to the closing team
They don't have enough good players on bench and they can only play well with the intensity of one match weekly. If the intensity is higher, like 2 or 3 matches weekly, they will not have enough player resource to do it well. Not mention about any case of injury or suspension.
Like in a match with Napoli, Lorenzo Pellegrini played after 2 weeks of unavailable and no training. He was not ready and did have a bad match for Roma.
I hope Napoli continue to have this squad. Because if they continue to have this squad, maybe they can continue to get successful results in the Champions League after a few years. They can even become a better team with a few accurate player transfers. If they manage to use this opportunity well, they can dominate Italian Serie A for many years. They have already managed to garner sympathy from around the world. Because everyone enjoys watching their matches.
It is unrealistic hope. With clubs like Napoli, they will have so many challenges after one successful season. First they will almost be impossible to repeat that success in a next one or two seasons so it will result in disappointment for their star players. Second they will not be able to satisfy demand of players to increase their salary. Net effects, they will lose most of their best players in one or two seasons.
