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."

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."

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.
