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.

Led by undefeated overall No. 1-seed Nebraska, the college volleyball elite will begin their quest for the 2025 national championship on Thursday, when the first round of the 64-team NCAA Division I tournament hits courts nationwide.

The Huskers are still chasing a perfect season, entering the 2025 title hunt on a 30-0 run having dropped just six sets all season — including losing just one set since September 16th.

"I was expecting us to be great, but certainly not undefeated," said Nebraska alumna and first-year Cornhusker head coach Dani Busboom Kelly on a recent episode of the Welcome to the Party podcast. "They continue to exceed our expectations."

Busboom Kelly's roster is loaded with the kind of experienced connection that only comes when the core of players have competed together for three straight seasons — an increasing rarity in the transfer portal and NIL era.

That said, this core has unfinished business on the national stage, with the superstar junior trio of middle blocker Andi Jackson, outside hitter Harper Murray, and setter Bergen Reilly — all AVCA Player of the Year semifinalists — looking to bring the first NCAA trophy in eight years back to Lincoln.

"It's such a special row, because we just know that all of us have been through thick and thin together and our bond is so strong," Jackson told USA Today Sports earlier this week. "[And Busboom Kelly] gives us so much confidence and we know that with her as our coach, we just can play fearless."

Stacked tournament field looks to spoil Nebraska's season

Even with their "fearless" play, a host of stellar opponents await Nebraska in the NCAA tournament gauntlet, hoping to play spoiler — including Busboom Kelly's previous program, the Louisville Cardinals, who await the Cornhuskers as the No. 2-seed in their own regional quadrant.

Fellow No. 1 seeds Texas, Kentucky, and Pitt will also chase their eventual chance at the Huskers via their own regionals, where the Longhorns could see arguably the stiffest competition from both No. 2-seed Stanford — the winningest program in NCAA volleyball history — and defending champion and No. 8-seed Penn State.

With tickets to the 2025 Final Four in Kansas City on the line, the NCAA volleyball bracket's 64 squads will start serving at 16 campus sites on Thursday.

How to watch the first round of the 2025 NCAA volleyball tournament

This year's NCAA volleyball finale begins when No. 5-seed Colorado takes on unseeded American University at 3 PM ET on Thursday, kicking off a two-day first round of 32 matches — with No. 1 Nebraska looking to handle Long Island University in their initial tournament tilt at 8 PM ET on Friday.

All games in the early rounds of the 2025 Division I tournament will air live on ESPN+.

US tennis star Coco Gauff continues to win off the court, with the 2025 French Open champion topping Sportico's list of the 15 Highest-Paid Female Athletes for the third consecutive year.

Fueled by $23 million in off-court endorsements, the $31 million earned by the 21-year-old world No. 3 WTA player edged out the $30 million total income that fellow tennis star and world No. 1 Aryna Sabalenka garnered in 2025.

Unsurprisingly, a full 10 athletes on the Sportico Top 15 list are tennis stars, a direct result of the fact that all four Grand Slams and the Masters 1000 tournaments boast equal prize money between the men's and women's competitions — a shift that began with the 1973 US Open.

That established expectation of gender equity in prize money has tennis far outpacing salaries in most other women's sports.

Also making the Top 15 are two LPGA golfers — world No. 1 Jeeno Thitikul (No. 15 on the Highest-Paid Female Athletes list) and US star No. 2 Nelly Korda (No. 7) — as well as popular Olympic skiier Eileen Gu (No. 4), WNBA superstar Caitlin Clark (No. 6), and USA gymnastics legend Simone Biles (No. 11).

Notably, Gu, Clark, and Biles as well as Venus Williams (No. 14) all proved the power of endorsements on this year's list, with nearly all of the quartet's earnings coming from sponsorship deals.

As WNBA CBA negotiations rage on, revenue sharing continues to be a wedge issue for both sides of the table, with the league office and the WNBPA eyeing the terms of the most recent proposal from differing viewpoints.

The Athletic reported on Wednesday that the WNBA believes it has offered the revenue-sharing salary model that the players have pushed for throughout the CBA talks, leaving athletes to claim 50% of the "sharable" portion of league revenue.

How the WNBA will determine the "sharable" cut is uncertain, though sources claim the compensation structure on offer will result in players taking home less than 15% of the league's total earnings.

That percentage is likely to take a further hit over the lifetime of a new CBA, according to the league's multi-year earning projections.

"I don't feel like there's any cultivation of a culture of trust [in the CBA talks]," WNBPA president and Seattle Storm star Nneka Ogwumike told The Athletic. "I feel like we've been heard, but not listened to, and I'm hoping that that changes in this 40-day extension, because what we want to do is get a good deal done."

Parental leave, draft combine, and more enters the WNBA CBA talks

Along with the issue of revenue sharing, the latest WNBA offer also reportedly outlined other proposals, such as the institution of a required offseason draft combine, the elimination of team housing, and the possible extension of the competition calendar by starting earlier and/or finishing the season later.

As for the WNBPA's Tuesday counteroffer, the players union is seeking to eliminate the core designation and shorten the current four-year rookie contract to three years.

The WNBPA is also asking to add non-birthing parental leave, retirement benefits, and reimbursements for mental healthcare.

The WNBA and WNBPA will meet again to negotiate sometime this week, with talks racing toward the second-extension deadline of January 9th, 2026.

After setting a new NCAA basketball record by scoring 100+ points in eight consecutive games, the No. 5 LSU Tigers will face their season's first true test when they visit the preseason-No. 7 Duke Blue Devils as part of the 2025 ACC/SEC Challenge on Thursday night.

"We don't play nobody in our nonconference schedule," senior guard Flau'jae Johnson told JWS in November. "From December on out, that's when it gets really [exciting]."

With their history-making string of lopsided wins under their belt, the Tigers will try to keep the streak alive against a now-unranked Duke side on a three-game losing skid.

The Blue Devils will rely on leading scorer and rebounder Toby Fournier for a spark, with the sophomore forward averaging 15.8 points per game despite Duke's 3-5 start.

As for LSU, the title-hunting Tigers will look to stat undefeated behind Johnson's team-leading 17.0 scoring average, as well as the 16.1 points per game put up by junior star transfer MiLaysia Fulwiley.

"Ballers just want to ball, like hoopers just want to hoop," Johnson said of LSU's quick cohesion this season. "You find different ways to bond and gel with teammates."
