Just like the first goal that already made by ac milan. Napoli's defenders were not using all of these the efforts to prevent the ball.
Anyone think that Napoli planned for this defeat to make AC Milan less careful in Champions League quarter final next 10 days?
With this big win, AC Milan gain two effects for Champions League match. First, they surely become more confident about themselves that they are strong enough to beat Napoli. Second, I don't know but probably AC Milan will become less careful for preparation in Champions League. If it is what they will do, they will be caught by Napoli and Spaletti. However I can not step in shoes of Napoli to know their plans and why they played like this.
This big win of AC Milan indirectly put Inter Milan to a risk of falling beyond top four. As of now, they have same points as AS Roma and behind them, Atalanta and Juventus are closely enough.
The victory won by Milan was beyond the predictions of many people, even Pioli himself was previously very pessimistic about this match. But this victory is certainly an important capital for the Rossoneri to face Napoli again in the Champions League. Although not seeded, Milan will be increasingly respected.
This victory is also very grateful for all Milanisti because they were able to survive in the top four. If you look at the results of Milan's previous matches, it is very unlikely that they will stay in the top four, but the additional three important points have made Pioli breathe a little easier.
