The Champions League returns for the 2025-26 season, and you can see all the action live in selected countries on DAZN.
The competition once again begins with the new league phase after it was introduced last season, and matchday one sees some huge games across three nights, including Arsenal's opener against Spanish side Athletic Bilbao.
The Gunners were among the top sides in last year's league phase, finishing with 19 points off six wins, one draw, and one loss. That was good enough for third place, which they parlayed into a run to the semi-finals before succumbing to eventual champions PSG.
Now the Premier League side looks to go at least one step further in their quest for silverware under Mikel Arteta, which has been hard to come by despite their consistent performances both domestically and in Europe.
Meanwhile, Athletic will take part in the league phase for the first time since its implementation last year. The La Liga outfit has had to wait 10 years to return to the Champions League, and their first test is a massive one at home against the London side.
DAZN News has all the information ahead of Athletic Club vs Arsenal
@viktorgyokeresAthletic Club vs Arsenal will take place at 5:45 pm BST on Tuesday, September 16, in the Champions League
That means that fans watching in the US and Canada can see the game at 12:45 pm ET and 9:45 am PT, while it's a 4:45 am kick-off on Wednesday, Sept 17, for fans in New Zealand.
Athletic Club vs Arsenal will take place at San Mamés in Bilbao, Spain.
The stadium opened in 2013 and holds 53,331 fans.
A key figure in Athletic's attack, the 23-year-old will look to unsettle Arsenal's stodgy defence with piercing runs down the left flank.
Williams can cause havoc with the ball at his feet, which the hosts will be counting on in their first Champions League match in a decade.
@AthleticClub
The Gunners' midfielder was unplayable at times during last year's Champions League, and his team will be relying on him to once again bring that form into the continental competition.
Rice is instrumental to the way Arsenal play the game, and he's at his best when he's influencing the match from the middle of the park.
A tough test out of the gates for both sides, but Arsenal's experience on this stage and willingness to grind out a result could be the difference.
Prediction: Athletic Club 1-2 Arsenal
