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.
There is no doubt that Ajax is a strong enough team. But with the form Napoli are in at the moment, and the way they've been able to continue to perform consistently well, it's very difficult to win against any team right now. Napoli has continued their good performances in both Serie A and the Champions League. As the players are in a good rhythm and they are now very confident, Napoli is more likely to win.
