Arsenal Women clinched the Super League title for the first time since 2012 with a 4-0 victory over Brighton.
Vivianne Miedema opened the scoring with her 22nd goal of the season after six minutes, the Dutch striker hitting a thunderous shot from the edge of the area which went in off the underside of the crossbar.
And the 22-year-old then turned provider after half an hour, setting up team-mate Katie McCabe to double the lead for Joe Montemurro's side at the Amex Stadium.
Beth Mead made it 3-0 with a superb long-range effort and Danielle van de Donk completed the rout in front of a record crowd of 5,265.
Miedema: I came to Arsenal to win
Miedema, who scored her 22nd goal of the season in Arsenal's 4-0 win, gave her reaction to their title success after the game.
"I came to Arsenal to win the league but I don't think I've realised what we've done yet.
"I'm happy we've done it and we've done it with a 4-0 win. Joe (Montemurro) changed a lot when he came in, so he has to take a lot of credit, but more than anything he really made us believe in ourselves."
Arsenal trio named in PFA's Woman's team
Vivianne Miedema is one of three players from champions Arsenal to be included in the 2019 PFA Women's Super League Team of the Year.
Mead: We are ecstatic
Mead said: "It's hard to describe right now but it's been a long time coming - everyone's ecstatic.
"Joe [Montemurro] says we've had a lot of ups and downs as a group with injuries and things like that so enjoy the moment."
Montemurro 'proud and honoured'
Arsenal manager Joe Montemurro said he was "proud and honoured" and praised his players for coming through a testing season.
"To coach an Arsenal team to a championship as an Arsenal fan is mind-boggling," he said. "It's something I'd never have thought about in growing up and becoming a coach. I'm very proud and very honoured to be here as an Arsenal coach.
Chelsea Women knocked out of CL
So-Yun Ji fired a fine free-kick home but Chelsea could not topple Lyon as a 1-1 draw proved enough for the reigning champions to reach their fourth-straight Women's Champions League final.
"Winning the title means a lot because we've had an interesting year. They've come together as a group and there's been a lot of adversity with regards to the injuries and so on. As a group, the love and the respect they have for each other really culminates in what we've achieved today.
"I'm very proud of the way we did it with control, defined our own destiny. We didn't have to rely on other teams dropping points or anyone else losing. It was just us and that's all credit to the players who were prepared every week and bought into the philosophy and methodology of play. They've represented Arsenal in the best way possible."
The Gunners have clinched the title with one game to play.
Their final game of the WSL season is against Manchester City at Meadow Park on Saturday, May 11 at 12.30pm.
