Scotland striker Julie Fleeting hit a hat-trick as Arsenal beat Fulham 6-2 to end the season as undefeated champions of the Women's Premier League.
Fleeting's goals have helped Arsenal claim two trophies
Jayne Ludlow, Angela Banks and Lianne Sanderson were the other Arsenal scorers in the league's final match of the season.
Gemma Ritchie and Holly Anderson replied for the Cottagers, who finished seventh in the table.
The Gunners have now won the League four times in the last five seasons.
And after also winning the Premier League Cup their trophy-count stands at a remarkable 21 in 14 seasons.
Defeats in the semi-finals of both the FA Cup and Uefa Cup meant they failed in their attempt to become the first British club to win all four major competitions.
But manager Vic Akers was nevertheless delighted with his team's efforts.
"We've got a great bunch of girls at the club and they've done us proud again," he said.
"It would have been nice to win the domestic treble and go through to the final of the Uefa Cup, which no English team has done yet.
"But every year we are in Europe we learn more and after reaching the semi-final twice, maybe we can go all the way next year."
