Not sure Napoli will win easily here due to the fact, in two matches they ended in draws. I agree Verona is not very good in defense, but it doesn't seem like a problem if Verona can score goals consistently in every match. But even so, I don't believe that Verona will win, because from such considerations it is very likely that the final result of this match is a draw again. If that happens, then their head to head record will get a draw in three consecutive matches.
I think Napoli will win this match not only because Verona are weak. Napoli have reasons to grab as many points as possible when Juventus, Atalanta and Roma can challenge Napoli position if they lose many points till the end of season. Napoli temporarily have a good position so they don't want to lose it too easily. Verona will be another victim of Napoli along their way to third position of Serie A, at least in this season.
Napoli will try hard to win the match against Verona. Napoli currently sits in 3rd place in the standings, of course a victory is highly expected against Verona in order to compete in the race for the Scudetto title. Napoli manager Luciano Spalletti hopes the players play well against Verona. However, it's a shame Napoli couldn't play Alex Meret due to an injury during training.
They will try to win in order to secure their third position firstly. Then if possible, they will try to race for Scudetto which currently have more advantages on AC Milan and Inter Milan. Meret is a good goalkeeper but his career is under-estimated because of other great goalkeeper in Italy. After Buffon, he has to stay under Donnarumma. Napoli are not strong with defense so the absence of Meret will affect their defense power that will decrease their ability to protect their goal. However, Verona are not strong enough to get points from Napoli.
