Considering that Napoli are the most consistent Serie A team, I think Milan will really face big problems when they face them in the Champions League. I think it's true that the quarter-finals are Milan's best achievement this season, but for something higher I think it's something that would be very surprising. Since Milan were draw to get Napoli as their quarter-final opponent, that's when I thought that failure would be easy for them.
Everything really looks in favor of Napoli, since Milan have not looked the best lately, I even doubted if they could beat Tottenham. By the way, on April 2, Napoli and Milan will play in Serie A, it will be a good rehearsal, but only this match will be in Napoli, and the teams will play the first match in the Champions League in Milan. Napoli is the clear favorite, but anything can happen.
