Adding to their already historic season, 2024/25 WSL champions and 2025 League Cup winners Chelsea FC handed Manchester United a 3-0 defeat in Sunday's 2025 FA Cup final, completing the club's second-ever domestic treble.

Though the Blues first claimed an elusive treble in the 2020/21 season, this year's roster did so without dropping a single match in any of the three domestic competitions.

"I could not have expected this," said first-year Chelsea manager Sonia Bompastor about her debut success leading the Blues. "It is almost ideal in terms of domestic dominance."

To clinch that dominance, Chelsea upended the defending FA Cup champs Manchester United at London's iconic Wembley Stadium behind a brace from French fullback Sandy Baltimore and a header from USWNT attacker Catarina Macario.

Baltimore gave Chelsea the lead by slipping a late first-half penalty past 2024/25 WSL Golden Glove winner and USWNT goalkeeper prospect Phallon Tullis-Joyce, and the Blues never relented, with second-half sub Macario doubling their scoreline in the 84th minute before Baltimore tacked on a final goal in stoppage time.

"It's a very emotional day," an emotional Macario told the broadcast after finishing her first season following a long ACL recovery. "It's a trophy we always wanted to win."

"All the credit to my players," said Bompastor. "We showed our mentality and our values in this game so we ended the season in an almost perfect scenario – we won, we were playing at Wembley, the stadium was nearly sold out, and we had a strong performance and result against a strong opponent."

"It is an almost ideal way to finish the season."

FA Cup crowds prove sustained demand for women's soccer

Chelsea FC's undefeated treble-winning season wasn't the only notable victory on Sunday, as the FA Cup final drew a crowd of over 74,000 fans for the third straight year.

Sunday's 74,412 attendance mark was just shy of both last year's crowd of 76,082 and the 77,390 fans who watched Chelsea defeat the Red Devils in 2023 — all well beyond the tournament final's previous record of 49,094 attendees achieved in 2022.

Fueled by the football fervor following England's 2022 Euro victory — the country's first international trophy, men's or women's, since the 1966 men's World Cup — the 2023 FA Cup final still stands as the largest crowd at a domestic women's soccer match across all nations.

With Sunday's match joining the over-74,000 attendance club, it's clear the post-Euros enthusiasm wasn't a blip, but a boost to the continued growth and sustained success of the women's game.

Following a dominant 2024/25 campaign, Chelsea FC will look to cap their historic run by completing a domestic treble on Sunday, when they'll battle Manchester United for a third season trophy in the 2025 FA Cup final.

After securing the 2024/25 League Cup in March amidst an unbeaten run to a sixth-straight WSL title, the Blues will close out their season against the league's third-place finishers, the Red Devils, in London's iconic Wembley Stadium.

Should Chelsea secure the 2025 FA Cup, they will add a second domestic treble to their resume after clinching their first trio of trophies in the 2020/21 season. This time, however, they could do so in undefeated fashion.

"We are in a really good place, just the fact that we won the league being unbeaten," said first-year Blues manager Sonia Bompastor. "To end the season with an FA Cup final at Wembley against Man United is maybe the perfect way to end the season."

Manchester United hunts second straight FA Cup trophy

Standing between Chelsea and the treble are 2024 FA Cup champions Manchester United, who will take aim at their only trophy of the season partly behind the play of 2024/25 WSL Golden Glove winner and USWNT goalkeeper prospect Phallon Tullis-Joyce.

Man United enter as the game's undisputed underdogs, having dropped both their WSL regular-season matches against Chelsea in narrow 1-0 defeats.

Even more, the Red Devils must overcome a particular tough stretch of play, facing more than a month without a victory on their schedule.

Man United's last win was their 2-0 FA Cup semifinal victory over Manchester City on April 13th, with the Red Devils suffering a pair of losses and recording two draws to close out WSL play.

That said, United has experience downing the Blues on the FA Cup stage, ousting Chelsea from last year's semifinals en route to a club-first FA title.

Remarking that Manchester United "are a really strong team," Bompastor pointed out that the Red Devils "don't concede a lot of goals, and we need to remember that."

"You only get the trophy if you win, so we need to make sure going into the game we have the best preparation and we perform on the day."
