Arsenal maintained their 100% start to the Women's Super League season with a hard-earned win over Birmingham City.

After a goalless first half, the Gunners broke the deadlock when Jordan Nobbs fired home from Beth Mead's pass.

Blues levelled within a minute through Emma Follis' finish from a tight angle, but Danielle van de Donk put Arsenal back in front from the penalty spot.

Nobbs steered home a Lisa Evans cross in injury time to seal a seventh league win in seven games for the Gunners.

Third-placed Blues had kept five clean sheets in their opening six games and frustrated Arsenal for long periods, although City keeper Ann-Katrin Berger did have to make fine saves from Nobbs and Mead.

When Follis dinked over Gunners keeper Pauline Peyraud-Magnin to immediately cancel out Nobbs' opener, it seemed Blues could become the first team to take a point off the Gunners - but Aoife Mannion's tug on Evans for the match-turning penalty proved to be a pivotal moment.
