Manchester City had to wait until the 94th minute to come up with a winner against Arsenal, claiming a 2-1 victory having gone behind to an early Vivianne Miedema goal. Sam Mewis equalised on half an hour before Caroline Weir took advantage of some chaotic Arsenal defending to turn in Georgia Stanway's blocked shot.
Manchester United remain out in front but struggled to overcome a determined performance from Reading. Leah Galton had put United in front only for Millie Turner to turn the ball into her own goal, allowing Reading back into the contest. Hayley Ladd headed United back in front late on to keep Casey Stoney's side three points clear of Chelsea.
The champions maintained their pursuit of United with a 1-0 victory at Brighton - Sam Kerr scoring the only goal of the game. There were emphatic wins for Tottenham and West Ham as the London clubs put their poor early-season form behind them.
US superstar Alex Morgan scored from the penalty spot to set Spurs on their way to a 3-1 win against Aston Villa. The Hammers were 4-0 victors against Bristol City, who remain rooted to the bottom of the table with just two points from their opening nine games.
Birmingham City's fixture against Everton was postponed due to a waterlogged pitch after torrential rain shortly before kick-off.
