Many people keep underrating Napoli that they cannot win the Champions League, the more you look down on Napoli the more the boys show more wonders, especially Victor. One thing about Champions League is that it is played home and away and if by mistake Napoli's able to beat you at their home, then they can get a draw at away. They have easily qualified. So the wrong thing to do is to underrate in-form team like Napoli where everybody is working their ass off in order to make the club proud.
Who will do that? They did not even understand football if they underrating napoli at this moment. None has been even seeing it as an underrated team. Napoli has become the favorite clubs to win UCL. 
As you can see most people will take the safe decision to pick napoli instead of ac milan. I think that people were not stupid enough like you said. Any team has a chance to win UCL right now even though the chance between any team may be different caused by it will be affected by some reasons.
The next opponent gonna be ac milan and napoli gonna pass it easily without a tough game against ac milan.
I think that you may see the wrong statement about napoli. Ac milan fans will always be thinking the club has bigger chance to win over napoli.
All the teams in the quarter-final round are very strong. There is no opportunity to think of any party as weak here. I think every team that qualified for the quarter-finals has the potential to qualify for the semi-final round. However, if we compare the performance of AC Milan with Napoli, then Napoli will be ahead. Because AC Milan's performance has deteriorated. This team has not won in the last three matches. In this situation, it is much more difficult for them to win the Champions League against Napoli. I decided to bet Napoli to win the first leg. Because it's Napoli's home match. Hope the Napoli team does not disappoint their fans.
