The Champions League will progress into the Round of 16 with just a single Serie A representative, after Atalanta’s remarkable comeback salvaged a disastrous campaign that nearly saw Italy unrepresented in the knockout stage for the first time since the current format was introduced in 2003-04.

Serie A's poor showing was punctuated by the elimination of its heavyweights. Ahead of Wednesday’s kickoff, Inter had been eliminated, while both Juventus, and Atalanta were all on the brink after heavy first-leg defeats.

Had all four entrants failed to progress past the knockout play-offs, it would have been the first time since 1987-88—when Napoli fell to Real Madrid—that no Italian team reached the first knockout round of Europe's elite competition.

With all four of her entrants nearly missing out as early as the round of 32 elimination playoff, Napoli much earlier in the league phase, this would have been the first year, since the reintroduction of the round of 16 that no Italian team has made it to the round.

By extension, there has been at least one Italian team in the last 16 of the Champions League, or first knockout round when it took other formats, every year since 1987-88, when Napoli lost out to Real Madrid 3-1 on aggregate after a 2-0 first-leg loss in the Bernabéu.

The one-time giants of Europe, who have produced three different winners of the competition - trailing only England, six - and have also combined for 12 titles, only third to Spain, 20, and England, 15, almost registered their worst piece of history in the competition but for Atalanta's heroics.

Nevertheless, their purple patch arguably ended much earlier, precisely around a decade ago, after Juventus' golden run in the competition could produce no climax, and Inter's success with Jose Mourinho back in 2010 remained their last title.

The Nerazzurri have been their proud representation in recent years, but despite playing in two of the last three finals, just like Juventus between 2015 and 2017, they could not deliver the title no thanks to losses to Manchester City and PSG.

This season was supposed to hold more promise, especially with the quartet of Juventus, Inter, Atalanta, and Napoli all lined up, and have comparative advantage to reach the playoffs given their league phase schedule.

However, Scudetto winner Napoli never gave themselves any chance from start to finish, Inter started as one of the best and finished as the worst, while Juventus got better along the way, but fumbled it in Istanbul.

Atalanta, their only survivor heading into the round of 16, had to pull a massive comeback against Borussia Dortmund, after suffering a 2-0 first-leg defeat in Germany a week ago.

It is the worst Champions League outing for Italian sides in recent years, and as all but one return home to only spectate the remaining 29 games in the competition this season, we take a look at their statistics, and facts surrounding this historic embarrassment.

Behind Serie A's historic UCL embarrassment: Stats and facts

Inter

Inter, who have reached two of the last three finals, went from blowing a chance as an overwhelming favourites for a spot in the top eight to losing a tie they were by a country mile favoured to win, as Bodo/Glimt displayed class over the two legs.

Despite a league dominance, which has seen them recently establish a 10 point cushion at the summit, they could not help but lost five of 10 Champions League games, including all of their final three at home to Liverpool, Arsenal, and Bodo Glimt.

Cristian Chivu's team started the competition with four straight wins, but finished with five defeats in their final six games, and for the first time in history, lost three consecutive European home games.

The elimination at the hands of Norwegian side is a new low for the Nerazzurri, who have never been dumped out of the competition by a club outside the Eurupe's top five leagues.

Juventus

The Old Ladies took on Galatasaray as rhe overwhelming favourites, but fumbled their chances after losing 5-2 in Istanbul, and even though they battled back with 10 men in Turin, and forced extra time, they ultimately lost 7-5 on aggregate.

Atalanta salvage Serie A embarrassment 

Atalanta, looking to overcome a 2-0 first-leg deficit, started very bright in the Gewiss stadium, with Italian striker Gianluca Scamacca firing them into the lead inside the opening five minutes.

Raffaele Palladino's side drew level on aggregate just before halftime thanks to Davide Zappacosta's deflected strike from outside of the box, a deserved cushion given their dominance, although Marco Carnesecchi had made huge stops to deny the visitors.

Mario Pasalic completed the comeback three minutes from the hour mark, but Karim Adeyemi came off the bench to peg them back and level the score on aggregate.

A moment of nightmare from goalkeeper Gregor Kobel saw him came off his line in the closing stages, failed an attempted clearance and forcing Ramy Bensebaini into a dangerous tackle that led to a penalty and second booking.

Lazar Samardzic converted the resulting penalty in the eighth minute of added time to secure a 4-3 aggregate win for the host, whose victory is much celebrated at home and appreciated by their domestic rivals, as it saved the face of the league.

What awaits Atalanta 

Arsenal or Bayern Munich awaits Gli Orobici when the round of 16 draw is carried out in Nyon, Switzerland, on Friday 27th, February 2026.

While Atalanta may not go all the way to the final just like Inter in past seasons, their progress from the previous round is a saviour of the reputation of Serie A, one-time biggest league of the world, but not enough to deny the truth of their diminishing standards.
