Minimal advantage for Milan at the end of the 1st seated opponent. In addition, the Milanese have a rather modest away record: the club has only 2 victories in the last 9 matches at a foreign ground, including 3 unsuccessful ones for Udinese.
Yes, Napoli have a little problem with the result (1 win in 4 matches), but the upcoming game is literally one of the most important of this season: the club will not miss the title, so reaching the semi-finals of the Champions League is a priority for this. Over-motivated hosts will go ahead, so I would expect an open game.
Admittedly, bets on OZ in the current play-offs show a critically low passability (only 3 out of 20 games), but in response from Italian teams, I would take a closer look at the goals of both teams. Of the last 6 personal meetings between the teams, 5 were played on “OZ: no”, so they should break through at some point. The quarter-final of the Champions League is a great moment for that.
