With the new Champions League season underway, besides favorites such as Paris Saint-Germain and Arsenal, 10 teams have been named as potential dark horses that could disrupt the competition. The ranking places teams such as Stuttgart and Como in the top 10, while Roma, Real Betis and Fenerbahce also appear in the original article.
Stuttgart and Como: Two Paths to Becoming Dark Horses

Stuttgart have shown inconsistent form at the start of the season, first suffering a heavy defeat against Bayern Munich before beating Cologne by a large margin. Head coach Sebastian Hoeness had previously been linked with Chelsea, Liverpool and Manchester United, but he remains in charge this season, while players including Angelo Stiller and Jamie Leweling have also stayed with the team. Stuttgart last played in the Champions League in the 2024-25 season, when they were eliminated in the league phase. Their previous run to the knockout stage dates back to the 2009-10 season.
Como are considered the most promising newcomers in this season's Champions League for producing an upset. The club has strong financial backing, and head coach Fabregas has shown tactical ability. Since being promoted in 2024, the team has impressed in Serie A, finishing fourth last season, one point ahead of AC Milan and two points ahead of Juventus.
Lille and the Other Candidates: Who Can Go Further?
Lille remain unbeaten in Ligue 1 and have also held Paris Saint-Germain to a draw. Their main opponents of a similar level in the league phase are Arsenal and Bayern Munich.
The ranking lists teams from No. 10 to No. 1, with Stuttgart at No. 10 and Como at No. 9. The original article does not provide the complete order or specific reasons for teams ranked No. 8 to No. 1, but it clearly conveys one view: these teams all have opportunities to create surprises in this season's Champions League rather than simply act as supporting players for the favorites.
Dark Horse Potential: Start by Looking at the League Phase
This ranking is not a prediction of the champion, but a selection of teams that could potentially make a meaningful run. Stuttgart need to get through the league phase, Como need to prove their fourth-place Serie A finish was not a coincidence, and Lille need to collect points against Arsenal and Bayern Munich. For Roma, Real Betis and Fenerbahce, reaching the knockout stage would already be a success.
The appeal of the Champions League lies in the breakthroughs of these non-favorite teams. Paris Saint-Germain are aiming for a third consecutive title, and Arsenal want to go further than last season, but the emergence of dark horses is often the biggest variable in the league phase. The next question is whether these teams can turn the expectations from the ranking into actual points and qualification.
