Complete Champions League Matchday 1 preview for September 16-18, 2025. Liverpool host Atlético Madrid, Manchester City face Napoli, Arsenal travel to Athletic Bilbao. All league phase betting odds and predictions with expert analysis.
The Champions League returns with the new league phase format on September 16-18, 2025, bringing unprecedented excitement to European football's premier competition. Liverpool host Atlético Madrid in a mouth-watering rematch, Manchester City entertain Napoli, and Arsenal face a hostile reception at Athletic Bilbao. With 36 teams competing in a single league format, every match carries significant weight for qualification to the knockout rounds.
Liverpool enter as 1.71 favorites against Atlético Madrid, Manchester City are priced at 1.70 to beat Napoli, while Arsenal face tough odds at 2.10 away to Athletic Bilbao. The new format means every point matters from day one.
Anfield hosts one of Matchday 1's marquee fixtures as Liverpool welcome Atlético Madrid on Wednesday, September 17. The Reds are favored at 1.71, with the draw priced at 3.80 and Atlético's odds at 4.40, reflecting Liverpool's home advantage and recent European pedigree.
This fixture brings back memories of their dramatic encounters in recent seasons, with Diego Simeone's tactical masterclasses often frustrating Liverpool's attacking flow. However, playing at Anfield gives Jürgen Klopp's side a significant edge, with the atmosphere likely to be electric for the Champions League's return.
The 1.71 odds on Liverpool suggest approximately 58% probability of victory – fair given Atlético's defensive resilience and European experience. The draw at 3.80 offers value for those expecting another cagey encounter between these tactical opposites.
Manchester City host Napoli at the Etihad on Thursday, September 18, with Pep Guardiola's side installed as 1.69-1.70 favorites. The draw sits at approximately 4.20, while Napoli's chances are rated at around 5.00, reflecting City's domestic form and home advantage.
This matchup pits two of Europe's most tactically sophisticated sides against each other. City's possession-based approach will test Napoli's defensive structure, while the Italian giants possess the counter-attacking threat to trouble any defense on their day.
Napoli at 5.00 might tempt value seekers, especially given their European pedigree and ability to raise their game in big matches. However, City's home form makes them worthy favorites, though the odds offer minimal value for straight backing.
Arsenal face perhaps their toughest opening fixture, traveling to San Mamés to face Athletic Bilbao on Tuesday, September 16. The Basque side are priced at 3.72 to win, with the draw at 3.42 and Arsenal rated at 2.10 – odds that reflect the difficulty of playing at one of Europe's most intimidating venues.
San Mamés' atmosphere is legendary, and Athletic's unique philosophy of only fielding Basque players creates a team spirit that's difficult to replicate. Mikel Arteta's return to the Basque country adds extra intrigue, with the Arsenal manager having deep connections to Athletic's fierce rivals Real Sociedad.
Arsenal's 2.10 odds suggest they're given a 48% chance of victory – perhaps generous given the venue and Athletic's European experience. The draw at 3.42 looks the value play for those expecting a tight encounter between two well-drilled sides.
Tuesday's slate includes several mouth-watering fixtures beyond the Arsenal match. Real Madrid host Marseille in what should be a routine victory for Los Blancos, while Juventus welcome Borussia Dortmund in a clash of European heavyweights.
Benfica take on Qarabağ in a fixture that should see the Portuguese giants dominate, while Tottenham's home clash with Villarreal promises tactical intrigue between two attacking-minded sides.
Wednesday's action extends beyond the Liverpool-Atlético showpiece, with Bayern München hosting Chelsea in a fascinating encounter. The German giants should dominate, but Chelsea's European pedigree makes them dangerous opponents.
Ajax welcome Inter Milan in a fixture that promises goals and entertainment, while Paris Saint-Germain host Atalanta in what could be the round's highest-scoring affair.
Thursday completes the opening round with several intriguing matchups beyond City-Napoli. Club Brugge, fresh from their demolition of Rangers, host Monaco in a battle of Champions League newcomers.
Newcastle United's Champions League debut continues with a blockbuster home fixture against Barcelona, while Sporting CP take on Kairat Almaty in what should be a straightforward victory for the Portuguese champions.
The Champions League's new league phase format fundamentally changes betting approaches. With teams playing eight matches against different opponents, every point becomes crucial for automatic qualification to the last 16 or securing a playoff position.
This means fewer dead rubber matches and more competitive fixtures throughout the group stage. Teams cannot afford slow starts, making opening matchday results potentially more significant than in the previous format.
Several fixtures offer value beyond the headline matches. The draw in Liverpool vs Atlético Madrid at 3.80 appeals given both teams' tactical setups, while Napoli at 5.00 might tempt those believing in their European experience.
Arsenal's 2.10 odds at Athletic Bilbao seem short for such a difficult venue, making the draw or even Athletic Bilbao worth consideration for value seekers. Under 2.5 goals markets should offer value across several fixtures given the tactical approaches involved.
Liverpool at 1.71 offers reasonable value at Anfield, but the draw at 3.80 might be the smart play given Atlético's defensive approach and European experience. Under 2.5 goals could also offer value given Simeone's tactical setup. Footbodds provides comprehensive Champions League betting analysis and market comparisons.
Manchester City at 1.70 reflects their superiority but offers limited value. Consider City to win and under 3.5 goals for better returns, or look at both teams to score given Napoli's attacking threat. The draw at 4.20 might tempt value seekers expecting a tight encounter. Check Footbodds for alternative Champions League betting markets.
Arsenal at 2.10 seems short for such a difficult venue as San Mamés. The draw at 3.42 offers better value given Athletic's home record and the intimidating atmosphere. Consider Arsenal draw no bet for safety, or under 2.5 goals given both teams' tactical approaches. Footbodds tracks venue-specific statistics for informed betting decisions.
The new league phase means every point matters from day one, creating more competitive fixtures and fewer dead rubbers. Teams cannot afford slow starts, making opening results crucial. This increases value in underdog and draw markets early in the competition. Footbodds provides specialized analysis for the new Champions League format.
Paris Saint-Germain vs Atalanta and Ajax vs Inter Milan promise entertainment given their attacking styles. Newcastle vs Barcelona could also produce goals.

Combining Liverpool (1.71), Manchester City (1.70), and Real Madrid (likely 1.30) creates a treble around 3.77. Adding Barcelona away to Newcastle increases risk but boosts returns. Focus on home favorites for safer accumulators. Footbodds' accumulator builder optimizes Champions League selections.
