I guess Napoli will be able to maintain their consistency after the World Cup. You say long vacations will degrade the performance of the players due to lifestyle and activities. But I don't think so. As they are professional athletes. So they will definitely be conscious about their fitness. And I think their performance will not deteriorate if their fitness is right.
As Napoli has been able to continue their good performances in both the Champions League and Serie A so far, they will not want their performance to suffer after the break. They will definitely be aware of this.
I agree with you, this is an important moment for Napoli so they will not waste it they have a greater chance of the title this season
I don't remember when the last time Napoli won Serie A so there is no reason for them to let this opportunity go
So far Napoli have undergone 12 games without defeat this is a perfect record if they keep it to the end of the season.
Last season too, Napoli started their season very well, but in the middle of the season, they lost the truck. And they could not win the title due to losing points in several matches. Napoli was 7 points behind title winners AC Milan. I think they have learned from previous mistakes. They will not make the same mistakes again and again. Napoli has been the most consistent team in Serie A and the Champions League this season. They certainly don't want this streak to end. Even if the players are on a long vacation, they must be conscious of their fitness. But if Napoli lose the truck after the break, I think we'll see the dominance of AC Milan in Serie A again.
