We're back with more women's football on Sunday, when the WSL returns with a full fixture programme. Hope you can join us then!

Chelsea get another corner which causes a few more problems for the PSG backline, but once again they can't force a save from the goalkeeper.

Chelsea get into PSG territory for the first time in a long while and win a corner.

If it stays like this until full-time, we'll go to extra-time and possibly penalties.
PSG will be hoping to get it wrapped up before then, given the dominance they've shown since half-time.

There looks like only one winner at the moment and it's the French side.
PSG go close to taking the lead for the first time in the tie but Ann-Katrin Berger plunges down to her left to deny Marie-Antoinette Katoto.
GOAL: PSG 2-0 Chelsea (2-2 agg)
