Europe’s premier club competition returns as the expanded Champions League league phase begins on Tuesday. The opening matchday features a slate of compelling matchups across three days, setting the stage for a chaotic and dramatic campaign. The spotlight falls heavily on the Bernabeu, where Real Madrid host Inter Milan in a rematch of last season’s knockout drama, while Arsenal travels to Naples to face Napoli.
This first matchday stretches across three days, with six matches daily as all 36 clubs in the expanded league phase begin their eight-game round-robin toward the knockout playoffs. It is a format built for chaos and drama in equal measure, and Matchday 1 sets the tone for the road ahead.
Tuesday’s slate also features Club Brugge hosting Aston Villa and Lille taking on Real Betis, but all eyes will be on the Bernabeu, where Real Madrid look to open their European campaign with a statement.
Tuesday
Game of the Day: Real Madrid vs. Inter
Player to Watch: Arda Guler, Real Madrid — The Turkish midfielder has emerged as a surprising early-season standout under Jose Mourinho, earning more minutes than expected in the attacking midfield. With 19 chances created, Guler leads all players across Europe’s top five leagues in the early weeks, showcasing exceptional vision and delivery. He will be a key creative force as Real Madrid looks to control the tempo against Inter.
Man of the Match: Kylian Mbappé, Real Madrid — Facing Inter at the Bernabeu provides the perfect stage for Mbappé to bounce back from a missed penalty against Real Betis. Having already scored four goals in his first four La Liga matches, the French forward is primed to make his mark on the European stage. A clash against his former club’s Italian rivals offers the ideal opportunity to remind Europe of his devastating capability.
Prediction: Real Madrid 3, Inter 1 — While questions linger about Real Madrid’s overall balance under Mourinho, the sheer quality of their attacking roster should see them navigate the league phase with style. Inter provides a tough test, but Los Blancos are favored to start their campaign with a win at home.
Best Bet: Kylian Mbappé to have 3+ shots on target (+130) — Mbappé’s shot volume remains consistently high, and despite competition for the left flank, he will be the primary outlet for Real Madrid’s attacks. Facing a defensive test from Inter, he is highly likely to register multiple shots on target as the hosts seek an early goal.
Wednesday
Game of the Day: Napoli vs. Arsenal
Player to Watch: Riccardo Calafiori, Arsenal — The Italian left-back has made a stellar start to the season in England, earning high praise for his early-season impact, which includes assists against both Coventry City and Aston Villa. Returning to Italy with Arsenal, Calafiori will look to impose his attacking threat against Napoli’s defensive setup.
Man of the Match: Christos Tzolis, Arsenal — The Greek winger has been one of the season’s early surprises, contributing three assists in his opening appearances. Facing a Napoli side still finding its footing under Massimiliano Allegri, Tzolis will have a major opportunity to shine in European competition and prove Arsenal’s attacking depth.
Prediction: Napoli 0, Arsenal 2 — Arsenal’s identity is well-defined, making them a difficult opponent to break down. Returning to the Champions League with renewed confidence, the Gunners are well-equipped to secure a positive result in Naples, where they will look to control possession and capitalize on counter-attacks.
Best Bet: Both Teams to Score (-126) — With key absences for Napoli but creative presence from Kevin De Bruyne, both sides will look to attack. Arsenal’s clinical finishing combined with Napoli’s defensive vulnerabilities suggests a competitive, open contest where both teams are likely to find the net.
Thursday
Game of the Day: Manchester United vs. Sabah FK
Player to Watch: Orphe Mbina, Sabah — Facing a historic club at Old Trafford is a monumental challenge for Sabah, a club celebrating its ninth anniversary around the time of this match. Mbina, who averaged over six shots per 90 in the qualifying rounds, will be central to any hopes of an upset as Sabah looks to make their historic debut.
Man of the Match: Bryan Mbuemo, Manchester United — After a strong start to the domestic season with three goals, Mbuemo is set to make his Champions League debut. Facing Sabah, the forward will be expected to deliver a performance worthy of the competition alongside Marcus Rashford and Benjamin Sesko.
Prediction: Manchester United 3, Sabah 0 — While Manchester United’s overall trajectory remains a topic of debate, they are heavy favorites against the Azerbaijani champions. Sabah’s historic debut at Old Trafford is likely to be a challenging one, with United expected to secure a comfortable victory.
Best Bet: Manchester United to score over 1.5 goals in the first half (+118) — With a Manchester derby looming on the weekend, manager Michael Carrick may rotate his squad, but United will still want to establish dominance early in their European home opener. Backing a quick start makes for a valuable play against a less experienced opponent.
