Yes! Napoli are currently playing well despite Lukaku's absence, but the management acted in time, providing Antonio Conte with a valid replacement for Lukaku.
I'm not surprised by the situation; it's what I would have expected from the reigning Italian champions.
Conte has managed to maintain Napoli's quality, even though they are playing without their star striker, Lukaku. However, the team still has players who can fill his position. Especially with De Bruyne, who can maintain the team's solidity, especially from midfield to attack. Unfortunately, Napoli's back line looks quite vulnerable at the moment. And if Conte doesn't fix this soon, I think Napoli will soon suffer a defeat due to their defensive weaknesses. Even in the match against Pisa, we saw how fragile Napoli's defense is. And clearly, this is not a small problem, but a major one that could cause Napoli trouble when playing against other strong teams. For example, in the UCL match, we saw Napoli lose.
