Of all the matches in the Top 8, I think this one is the hardest to predict, given that Napoli and AC Milan were pretty evenly matched in the first leg.
AC Milan won the first leg 1-0, in other words they beat Napoli twice in April, so there is no doubt that they will have a psychological advantage before this second leg.
However, Napoli's coach Spaletti confirmed that the team's top scorer Vitor Ossenhan will be back for the second leg even though he avoided the first leg due to injury. I think Vitor Ossenhan's speed, power, positioning and most importantly, control are crucial to the team, and I believe he has the ability to rewrite the game this time.
Napoli's offense is mainly focused on the left side, as Chivarasquilla and Schilenski, who was the most threatening player in the first leg, are quite compatible with each other, and both players often provide assists for Vitor Ossenhan, so AC Milan's right side players will need to give their best performance.
Before the first leg, I mentioned that AC Milan's Rafael Raphaelio and Bacondyas are quite dangerous, and it's true. Rafael Raphaelio was very fast in the attack, while Bacondeias showed a great turn in the middle of the midfield during the team's goal, which showed his value. Napoli will have a great chance to press forward in the next round, and when AC Milan get the ball, they will try to send it to Rafael Rio and Bacondeias for a quick counter-attack.
However, with Vitor Ossenhan back in action and the full support of the Napoli fans, I believe the hosts will be able to bounce back and advance to the last 4.
