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.
