Personally I think the second leg is really unpredictable. Napoli will certainly play Osimhen from the first half, it will definitely increase their strength in attack. While the two teams have comparable chances even if Milan lead the first leg with a victory. I would not fully think Napoli will fail, but I tend to think Milan can advance to the next round this season.
Anyone can still qualify from this quarter-final stage, but perhaps what is less interesting is that we will again see two Serie A teams likely to batlle in the semi-finals. Inter is very likely to qualify, so one between Napoli and Milan will meet Inter in the semi-finals.
this is what the Napoli coach must pay attention to, if he plays Osimhen to starter then is worried that he will become a target for Milan's back line and has a high chance of getting injured again, especially since leg 2 is what determines which team will continue to the next round
the best decision was to play osimhen in the second half while in the first half napoli had to use a defensive system but I'm sure spalletti has a better strategy than I thought and the match in leg 2 is really worth watching
