Milan won their UEFA Youth League group, while Juventus and Inter went through in second place, the Bianconeri ending with a chaotic 4-4 draw against their PSG counterparts.
While the Champions League group phase comes to a close this evening, the same is true of the youth version of the tournament.
Napoli were unable to replicate the form of their senior squad, scraping just one point from a group won by Liverpool, with Ajax in second place and Glasgow Rangers third.
Milan were the only Italians to win their UYL group on 14 points ahead of RB Salzburg, with Chelsea at rock bottom.
Inter finished runners-up to Barcelona in Group C, on seven points to 14, still pushing out Bayern Munich on just six points.
Juventus get the play-off spot in Group H after taking second place behind PSG, beating out Benfica.
Their group concluded in chaotic fashion this afternoon, as Juve were losing 4-1 at home to Paris Saint-Germain up until the 89th minute.
That is when Kenan Yildiz, Dean Huijsen and Lorenzo Anghelè sparked an extraordinary comeback to draw 4-4 with three goals in the space of five minutes.
