The absence of Lukaku did not prevent Napoli from winning, i agree with that, but it was clear that the team missed him. Lucca has not yet adapted and managed to do very little. That’s why there were two players who i said before the start of the season would be a tandem, and those are McTominay and KDB. A fantastic performance from these two players and also KDB’s first goal in the very first match. I also watched Roma, and even though it was only 1-0, they displayed excellent football. As for Milan, that had to be much better, of course luck was not on their side unfortunately. We saw Modric and Pavlovic, but in my opinion, that is still not a well coordinated team.
Napoli doesn't rely solely on one player, so Lukaku absence won't hinder Napoli from defeating any team. Their players have a built-in mentality to win Serie A. Everyone players will always give their best, and I'm confident that with their current form, Napoli will once again challenge for the title and strive to defend it this season.
Yes, Roma played well against Bologna yesterday, scoring one goal, which is their best result. Bologna is not a small club in Serie A, so at least Roma has shown significant improvement this season.
