Having spurned a golden opportunity just moments earlier, Lauren James provided a sumptuous assist for Sam Kerr to break the deadlock after 30 minutes of action at Stamford Bridge.
The England star cut inside off her left flank, bamboozled the Paris defence with a mesmerising stepover, and clipped a beautifully-judged cross towards the far post, with Kerr on the spot to provide the finishing touches.
Yet within just eight minutes, the visitors were back on level pegging after an awkward looping header from Thea Greboval from a corner snuck into the top-right corner to stun the hosts.
