After beating Bristol Academy 2-0 on Sunday to progress through to the FA Cup Final, Arsenal got off to a flyer in this midweek League fixture against the same opponents, scoring three goals within the first 11 minutes.
Lianne Sanderson grabbed the first almost immediately from the kick-off. Arsenal's first attack resulted in a goalmouth scramble that the striker latched on to quickest.
Four minutes later Katie Chapman doubled the score after she brushed off a defender to slot home.
Rachel Yankey then put the game beyond Bristol in the 11th minute with the best goal of the game, a fine 25-yard strike that Bristol's keeper could do nothing about.
However Bristol grabbed a controversial penalty on 41 minutes after Anita Asante handled the ball in the box, after confusion over whether the play had been resumed on a Bristol free-kick.
Captain Corrine Yorston stepped up and converted the penalty to make it 3-1 at half time.
In the second period Sanderson looked most likely to add another goal after going close on several occasions. And on 82 minutes she did. The 19-year-old rounded two defenders on the edge of the box before firing home a fierce shot to make the final score 4-1.
Arsenal now sit five pionts clear of second-placed Everton. This Sunday they travel to fourth-placed Leeds before meeting Charlton for the first time on Thursday 29th March at Borehamwood FC. Kick-off 7.45pm.
