Arsenal stretched their lead to eight points at the top of the Women's Premier League with a comfortable 4-0 win against Cardiff City Ladies.
England winger Karen Carney gave Arsenal the lead after 14 minutes but Cardiff kept the champions at bay until early in the second half.
Chapman then scored her second, and Arsenal's fourth, with 18 minutes remaining to maintain Arsenal's 100 per cent record in the league this season.
The game took place at Hoddesdon Town FC due to unplayable conditions at Boreham Wood.
Arsenal's next fixture is against Doncaster Rovers at Keepmoat Stadium on Wednesday night. A win from their final game in hand would put the champions 11 points clear of Leeds United. Arsenal then take on Leeds for the first time this season in next Sunday's League Cup Final.
