Chelsea FC are vying for a bit of UWCL revenge this week, as the perennial Champions League contenders take on 2024/25 finalists Barcelona in the 2025/26 campaign's league-phase slate on Thursday.

Last season's runners-up have ousted Chelsea in the Champions League semifinals two years in a row, with Barcelona going on to win three of the last five tournament titles.

Unfortunately for the Blues, Barcelona have never lost at Chelsea FC's Stamford Bridge home pitch — and they're one of just three 2025/26 Champions League clubs to maintain a winning record so far this season.

Chelsea won't be the only WSL titan to host a Spanish side this week, as reigning UWCL champs Arsenal look to bounce back from a frustrating 1-2 league-phase start against Real Madrid on Wednesday.

"I think it's easier to get to the top than staying at the top," Arsenal coach Renée Slegers said of her team's losing run. "We have high expectations on ourselves because we know what we're capable of. At the same time, I know that the squad is really good at being in the moment, taking it game to game, and preparing as well as possible to be able to execute."

Reigning UEFA Women's Champions League winners Arsenal suffered a setback on Wednesday, falling 3-2 to German side Bayern Munich after a second-half collapse led to three unanswered goals.

The Gunners are now 1-2 in league phase play, landing them in 11th place with three opening-round matches remaining.

"It's not good enough. We don't want to concede three goals in one half in the Champions League," Arsenal manager Renée Slegers said postgame. "It's everything. It's keeping the ball, making better decisions on the ball in their half to keep the ball there for longer, because it was very transitional."

A bright spot for Arsenal came via an opening goal from USWNT defender Emily Fox — one of a few US-centric Champions League boosts this week.

USWNT forward Catarina Macario notched a brace in Chelsea FC's 6-0 drubbing of St. Pölten on Tuesday, a match that also handed USWNT defender Naomi Girma her 2025/26 Champions League debut with the Blues.

Tuesday's clash also saw Chelsea captain Sam Kerr find the back of the net twice, as the Australia standout made her first start in 692 days.

Now halfway through league-phase play, only Barcelona, OL Lyonnes, and Manchester United remain perfect with a trio of wins, with Champions League matches resuming on November 19th.

OL Lyonnes scored some UEFA Champions League revenge on Tuesday, upending reigning UWCL champs Arsenal 2-1 in the powerhouse pair's 2025/26 league phase opener in London.

In a rematch of last season's Champions League semifinal, Haiti international Melchie Dumornay sealed the OL Lyonnes result with a first-half brace for the French titans, quickly countering Arsenal forward Alessia Russo's seventh-minute strike.

"Errors happen from time to time, but if they happen too often, of course, there's something there," noted Arsenal head coach Renée Slegers, referencing the defensive mistakes that led to both OL Lyonnes goals. "Sometimes it's intangible or hard to put your finger on because it's a mixture of things."

"We won't get too high [or] too low in this situation," the Gunners manager continued, adding "the team went through hard times last year as well, and then we ended the season on a high with an amazing achievement in the Champions League."

OL Lyonnes weren't the only opening-day league phase victors, as Juventus took down Benfica 2-1 while 2024/25 runners-up Barcelona demolished Bundesliga side Bayern Munich 7-1 behind a pair of braces from attackers Ewa Pajor and Clàudia Pina.

Unlike previous iterations, the 2025/26 Champions League format does not include first-round rematches, with each team facing six different opponents before advancing to the knockouts.

UWCL league phase opening matches conclude with five games on Wednesday, with WSL winners Chelsea FC kicking off the action against Dutch side FC Twente at 12:45 PM ET.

On Tuesday, 2024/25 UEFA Champions League winners Arsenal announced that the Gunners are making the 60,704-capacity Emirates Stadium their permanent home for all WSL matches on the heels of last season's successful nine-game run in the north London venue.

Arsenal dominated the WSL in attendance during their 2024/25 campaign with a total of 415,000 tickets sold, a 20% increase over the Gunners' 2023/24 season.

Even more, the club averaged crowds of over 34,000 fans for the team's nine matches hosted at the men's side's historic Highbury home.

Both Arsenal's and the league's season-high attendance came in February, when 56,784 fans packed Emirates for the Gunners' North London Derby match against Tottenham.

While all of Arsenal's 11 WSL home games will kick off at Emirates, the reigning European champs will open their UWCL defense at the significantly smaller, 4,500-capacity Meadow Park, with future Champions League matches moving to Highbury should the Gunners advance to the tournament's knockout rounds.

"For us, this is just the beginning, and bringing every WSL match to the Emirates is another step for more supporters to be part of this special journey," said Arsenal head coach Renée Slegers in a club statement. "We'll come back next season, with fire in our hearts, more determined, more ambitious, and more together than ever."

As the 2024/25 UEFA Women's Champions League (UWCL) wraps up its two-leg semifinals on Sunday, the English teams still in the running find themselves on the brink of elimination from Europe's most prestigious club competition.

Facing a 4-1 deficit against reigning champs Barcelona, Chelsea will aim to close the gap — and keep their historic quadruple hopes alive — at home this weekend.

Meanwhile, Arsenal will try to overcome a more manageable 2-1 deficit against eight-time Champions League winners Lyon, traveling to France to keep their UWCL campaign alive.

An English side hasn't won the UWCL since 2007, when Arsenal took home the WSL's lone European championship trophy.

"Huge respect for their history and what they have been doing and producing in the Champions League, in Europe," Arsenal manager Renée Slegers said of Lyon. "I think they're still a very strong side."

"Subconsciously, you always have that thing when you fall short, like last year," said Lyon midfielder and USWNT captain Lindsey Heaps, reflecting back on last season’s title loss to Barcelona. "You lose a game, you lose a tournament – the feeling is there until you're back in the the games that can fix that feeling."

How to watch the 2024/25 Champions League semifinals

Sunday's second leg of the 2024/25 Champions League semifinals kicks off with Chelsea vs. Barcelona at 9 AM ET, before Arsenal faces Lyon at 12 PM ET.

Both matches will air live on DAZN.

The 2024/25 UEFA Women's Champions League semifinals begin this weekend, as four powerhouse clubs familiar with the UWCL spotlight kick off their first matches of the two-leg round.

France's Olympique Lyonnais, Spain's Barcelona FC, and England's Arsenal and Chelsea will battle it out, with just two tickets to the winner-take-all May 24th final in Portugal on the line.

"The coolest thing about big tournaments and high-stake games is you might be expecting something, and you get something completely different," Olympique Lyonnais midfielder Lindsey Heaps told reporters this week. "That's when you see the best teams come out, and they're able to adjust."

Champions League semis pit WSL against European elite

Arguably topping the four-contender list are defending champs Barcelona, with the Spanish side hunting a fourth UWCL title in five years. First, however, they'll have to contend with a stacked Chelsea team hungry to lift a first-ever Champions League trophy — one that could clinch a historic quadruple.

Meanwhile, with both the men's and women's sides reaching this season's Champions League semifinals, Arsenal will square off against eight-time champions Lyon in a quest to claim their first UWCL title in over 18 years.

Both WSL titans are chasing history against their European opponents, with Arsenal still the only UK team to ever win Champions League.

The Gunners will kick off the round by hosting Lyon in their 60,000-capacity Emirates Stadium.

"Playing at the Emirates, and the hunger and the belief that we have as a team at the moment, we're going to go and play our game to the best we can," said Arsenal manager Renée Slegers.

With an estimated 40,000 tickets sold for the pivotal clash, Emirates provides an environment even Arsenal's opponents look forward to competing in.

"You always want these kind of crowds and this kind of atmosphere," Heaps said of the Saturday matchup. "Even if it's against you, it's the best thing in the world."

How to watch the 2024/25 UEFA Champions League semifinals

The first-leg matchups of the 2024/25 UEFA Champions League semifinals kicks off on Saturday, when Arsenal hosts Lyon at 7:30 AM ET.

Then on Sunday, Chelsea will travel to Barcelona to take on the reigning champs at 12 PM ET.

Both matches will air live on DAZN.

An age-old rivalry headlines the WSL this weekend, as second-place Arsenal gears up for Sunday's Stamford Bridge showdown against league leaders — and reported recipient of USWNT star Naomi Girma — Chelsea FC.

Both clubs are on an undefeated tear, with Chelsea yet to register a loss halfway through the 22-match 2024/25 season.

Meanwhile, newly minted head coach Renée Slegers's Arsenal will attempt to avenge the Gunners' lone loss — a 2-1 October stumble to first-season WSL boss Sonia Bompastor's Blues.

Chelsea and Arsenal's dominance goes beyond the WSL, as both sides also advanced to the semifinals of the League Cup with massive shutout wins this past Wednesday.

Wright shines spotlight on WSL investment debate

A product of a system that often places men's and women's teams under the same leadership, Chelsea and Arsenal have set the standard for the top-flight UK league — and cast other clubs in their shadow.

As some WSL teams continue to snag top international stars, those seeing departures risk falling by the wayside — putting into question a system that might be inhibiting the league's growth and parity.

"In England, with the women's league, I believe if you gave some owners the opportunity to back out of supporting the women's game, I think they would, simply because I feel like they're all about profit," Arsenal legend and outspoken women's football advocate Ian Wright told The World Economic Forum in Davros this week.

Wright acknowledged that the women's game, which suffered from a near 50-year FA ban, is still "playing catch up on every level, infrastructure, training, coaching and every level of development."

"Because of the past it wasn't allowed to be built up, so we are trying to do that now. So, it needs owners, individuals and corporates that will invest."

Currently, the English FA is considering expanding the lower tiers of the women's football pyramid to incentivize development and professionalization at the club level.
