Arsenal started their Women's Super League campaign in the best possible way with a comfortable 4-0 home win against a 10-woman Brighton, aided by Beth Mead's brace.
Emma Kullberg was sent off early for the visiting Seagulls, and Kim Little put the Gunners in front halfway through half-time.
Stina Blackstenius hit the bar late in the first half, as Arsenal tried to make the extra person advantage count.
They pushed further ahead in the second half with goals coming from Blackstenius and then Mead's double, as Jonas Eidevall's Arsenal side try to go one better than their second place in the WSL table last season.
