The 2025/26 Champions League quarterfinals have arrived, as WSL rivals Chelsea and Arsenal prepare to kick off an historic London derby in the round's first leg on Tuesday — with both UK clubs contending with shorthanded rosters after waning midseason availability.

Chelsea is without Australian standouts Sam Kerr and Ellie Carpenter as they return from their second-place run at the 2026 AFC Asian Cup, while fellow Matildas Caitlin Foord, Steph Catley, and Kyra Cooney-Cross sit out for Arsenal.

The Blues' concerns go even deeper, however, as the recent departures of Guro Reiten and Catarina Macario combine with a long injury list: Aggie Beever-Jones remains questionable, while Millie Bright, Nathalie Björn, Mayra Ramírez, and Niamh Charles are all sidelined.

"I still think we have a lot of quality and coming into the game tomorrow, we will have some strengths to use," assured Chelsea manager Sonia Bompastor on Monday.

The other Champions League quarterfinal matchups should showcase more star power, as Wolfsburg takes on OL Lyonnes, Barcelona opens its Clásico against Real Madrid, and Manchester United battles Bayern Munich.

"You know it's going to be competitive — nobody's going to give anything away for free," said Barcelona forward Caroline Graham Hansen.

With the 18-team UWCL league phase now done and dusted, the 12 clubs still standing discovered their paths to the Final in the 2025/26 Champions League knockouts draw on Thursday.

While the top four clubs — No. 1 Barcelona, No. 2 OL Lyonnes, No. 3 Chelsea FC, and No. 4 Bayern Munich — punched their way into March's quarterfinals behind elite league-phase performances, the remaining eight teams must battle in February's playoffs in order to advance.

Thursday's draw has reigning champs No. 5 Arsenal facing Belgian side No. 12 Oud-Heverlee Leuven in the playoffs, but the Gunners then face a difficult road in the UWCL knockouts, staring down a potential quarterfinal clash with WSL rivals Chelsea as eight-time UWCL winners OL Lyonnes looms on the same side of the semifinal bracket.

Elsewhere, No. 7 Real Madrid have an opportunity to make UWCL history should they win their playoff tie against No. 10 Paris FC, setting up the tournament's first-ever El Clásico with a possible quarterfinal match against perennial winners Barcelona.

The UWCL's first-ever league phase wraps on Wednesday, when all 18 2025/26 Champions League clubs will square off in a simultaneous afternoon kick-off finale.

Top finishers No. 1 Barcelona and No. 2 OL Lyonnes already secured automatic spots in the quarterfinals, with similarly unbeaten No. 3 Chelsea looking to claim their spot with a result on Wednesday.

The fourth guaranteed pathway will be tougher fight, however, as just three points separate No. 4 Juventus and No. 11 Atletico Madrid on the Champions League table.

While the top four teams will advance directly into the March quarterfinals, clubs finishing fifth through 12th will instead move on to the European competition's first-ever knockout playoffs in February to determine the final quartet of quarterfinalists.

No. 4 Bayern Munich, No. 5 Real Madrid, No. 6 Juventus, No. 7 Wolfsburg, No. 8 Arsenal, No. 9 Manchester United, and No. 10 Paris FC have all netted enough points to at least make the playoffs, leave three teams — Atlético de Madrid, No. 12 Oud-Heverlee Leuven, and No. 13 Vålerenga — battling the final two spots.

Amid Wednesday's high-stakes matchups, Wolfsburg will look to break into the upper ranks against Chelsea, Juventus will try to hold off Manchester United, and 2024/25 champs Arsenal will shoot for a result against Oud-Heverlee Leuven.

Wednesday's final UWCL league-phase matches will be cutthroat battles for tournament seeding.

The action kicks off at 3 PM ET, with live coverage on Paramount+.

With just one league-phase matchday left, a trio of unbeaten clubs — Barcelona, OL Lyonnes, and Chelsea — stand alone atop the 2025/26 Champions League table, leading the 18-team pack after all three squads notched midweek wins.

No. 1 Barcelona and No. 2 OL Lyonnes each have 13 points, with the Spanish contenders earning the edge over their French counterparts with a +15 goal differential.

Meanwhile, Chelsea sits in third with 11 points following a 6-0 drubbing of No. 17 AS Roma on Wednesday, though the Blues will need a result against No. 7 Wolfsburg next week to secure a spot in March's quarterfinals with a top-four finish.

Though the byes into the quarterfinals are still up for grabs, with just one matchday left before the knockouts, several of Europe's biggest teams have qualified for February's playoffs.

Wolfsburg alongside No. 10 Paris FC, No. 9 Manchester United, No. 8 Arsenal, No. 6 Juventus, No. 5 Real Madrid, and No. 4 Bayern Munich have already racked up enough points to advance out of the league phase.

Three clubs — No. 13 Vålerenga, No. 12 Oud-Heverlee Leuven, and No. 11 Atlético de Madrid — are fighting for the two remaining playoff tickets, with December 17th's simultaneous kickoff set to determine the winners.
