The WSL title race appears to be a genuine four-way fight this season after a huge weekend at the top of the table.
It still feels relatively early in the season but this was a weekend that had a seismic impact, including a clash between two of the main protagonists at the Emirates Stadium. Chelsea may have ended it at the summit but games in-hand for rivals mean it is still neck-and-neck.
Alessia Russo was the hero as Manchester United secured a memorable win over Arsenal on their first visit to the Emirates, turning a 2-1 defeat into a 3-2 victory in the final minutes. The England forward headed home a 90th-minute winner, deciding a see-saw contest that showed the domestic game at its most dramatic.
