How... How did Lauren James not score? It was genuinely harder to miss?
She couldn't believe it either!
Chelsea 0-0 Paris FC

Someone should check the temperature of Lauren James' head because that is not like her to not even hit the target.
Last week you would have bet your mortgage on her to score, glad I didn't do that there!
Chelsea 0-0 Paris FC
Ohhh! Paris FC mix-up at the back and Lauren James is found unmarked in the box, but James sends her effort a good way wide of the far post. Big chance missed.
Chelsea 0-0 Paris FC
Paris FC stop Chelsea in their tracks again.
Lauren James tries a one-two with Sam Kerr but her pass is slightly behind the Australia forward and the visitors get back to snatch the ball.

Chelsea have given the ball away a few times now. Two have led to attacking opportunities for Paris FC, while the latest knock-down from Sam Kerr went straight to an opponent. Emma Hayes let out a cry of frustration in front of us.
Chelsea 0-0 Paris FC
Sam Kerr breaks free on the wing and tries to cut the ball back to Lauren James, but her pass lacks the needed power.
Chelsea 0-0 Paris FC

Paris FC have brought a bit of physicality to this contest.
It is clear that they saw what Real Madrid did last week and wanted to replicate it, wanted to try and rough Chelsea up a bit and throw them off their normal game.
Sometimes it takes Chelsea too long to have that aggression and bite back. They can't afford to do that tonight because Paris FC have a dangerous frontline and can hurt them.
Chelsea 0-0 Paris FC
Paris FC are second in the French top flight and they're playing like it.
Lou Bogaert charges towards the Chelsea defence but is fouled.
Their momentum is stopped and Chelsea manage to recover after the free-kick.

Paris FC forward Clara Mateo looks a threat. She's managed to draw a few defenders out already.
Niamh Charles is putting in some hard yards down the left-hand side and has occasionally been covered by Ashley Lawrence, coming across from the far side.

Every time the ball comes central Paris FC are pressing very high, which is exactly what Real Madrid did last week.
Chelsea can't afford to let them turn the ball over so high up the pitch.
Chelsea 0-0 Paris FC
More pressure from Paris FC!
Mathilde Bourdieu is one-on-one and has a chance in front of goal but fires straight at Ann-Katrin Berger.
Chelsea 0-0 Paris FC
Clara Mateo has been lively and is threaded through on goal before the referee pulls the play back for a foul earlier in the build-up.
Chelsea 0-0 Paris FC
Paris FC have caused Chelsea some trouble already.
Clara Mateo and Julie Dufour try to work an opening on the edge of the Chelsea box but can't find a way through.

Lauren James is already moving in and overloading the midfield, she's coming inside into the pocket, almost second number ten alongside Jessie Fleming.
That then enables Niamh Charles to get forward on this left-hand side - she is moving very high into the space left by James.
Paris FC are going to have to keep an eye on that as it will likely cause a lot of problems.
Chelsea 0-0 Paris FC
More promising from Chelsea.
Lauren James pings the ball across to Jessie Fleming who cuts inside and tries to take a shot at goal but it's deflected and easily caught.
