Arsenal won the double last season but have had to settle for the runners-up spot in both the Southern Division and League Cup this term.
The Gunners and Vixens had met twice in the league in 2017, with Arsenal comfortbaly winning both games, 5-1 at home in January and 4-1 away in March.
But when it came to the cup final, Bristol pulled off a very different result.
Goals from Paige Sawyer, Lauren Hemp, Katie Jones and Aimee Palmer saw the Vixens to an impressive 4-0 victory.
