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.
