Arsenal face the toughest test of their Women's Champions League campaign so far on Thursday night when they visit holders Barcelona at the Camp Nou. The matchday four tie kicks off at 18:45 CET (17:45 GMT) and brings together two of the three unbeaten sides left in the league phase.

Two unbeaten sides meet

Barcelona have won all three of their league-phase matches and have scored 19 goals in the process, including an 8-0 victory over HB Koge. They sit second in the table on nine points, one behind OL Lyonnes, who thrashed Juventus 6-0 on Wednesday. Arsenal are also unbeaten, with seven points from their three matches, and victory in Barcelona would take them level with Lyonnes at the top.

A repeat of the 2025 final

The match is a repeat of last season's final in Lisbon, which Arsenal won to lift the trophy. Barcelona have changed since then, losing several big-name players, but have kept winning, and the BBC notes that the Spanish champions have coped well despite the departures. Arsenal, meanwhile, have made an unbeaten start of their own and will need to stop the most prolific attack in the competition to keep it going.

What is at stake

With only six league-phase matches per team, victory for either side would be a major step towards the knockout rounds. Barcelona would move onto 12 points and strengthen their grip on a top-two finish, while an Arsenal win would shake up the top of the table. The other match on Thursday sees Benfica host Austria Wien at 21:00 CET. Source: UEFA | Source: Flashscore
