However they cannot underestimate the power of Napoli, Napoli humiliated Liverpool in their first match in the Champions League with a convincing score of 4-1. They now lead the table with two wins, it's a good record even though this match they acted as guests. It is very possible for Napoli to win this match.
In this case I may agree with you about Napoli but for a win I still feel Ajax will still stand as winners.
Regardless of what Napoli did to Liverpool the longer they played the more difficult it was for them to rotate players and it was proven last season they failed in all competitions due to difficulties in maintaining form.
Now the schedule is getting tighter so I am quite sure of Ajax in this match.
Here as right now both teams are playing with this most chances Napoli is going to be better team but still we have to keep this in mind Ajax playing at home, and they could be no easy opponent for Napoli in these conditions and quality of the game they are also having few best players in business, and they can do much better than expectations Napoli ruin Liverpool at home, but now they are on road, and they have to be tough if they want to some positive from this match.
Ajax's start of this season is also very good, and they have done good game against Liverpool in Anfield but unlucky as they come out without any point, but now they are host and have fair chance for keeping them into chance for next round with this win against Napoli at home.
