Erin Cuthbert kept Chelsea's Champions League hopes alive as she dragged them back into their semi-final clash with holders Lyon.

The Blues suffered a 2-1 first-leg defeat in France, but retain hope ahead of next Sunday's return at Kingsmeadow thanks to Scotland international Cuthbert's second-half strike.

Emma Hayes' side fell behind in front of a crowd of 22,911 when defender Magdalena Eriksson inadvertently deflected Delphine Cascarino's shot past goalkeeper Ann-Katrin Berger.

But they looked to be in deep trouble after Amandine Henry handed five-time winners Lyon a 2-0 lead before the break.

Chelsea's fortunes did not improve on the stroke of half-time when, after Ramona Bachmann had been brought in the box down by Eugenie Le Sommer, Fran Kirby saw her penalty saved by Sarah Bouhaddi.

However, the visitors finally grabbed a lifeline when Cuthbert fired in a fine half-volley from substitute Beth England's knock-down to blow the tie wide open. 

In Sunday's other semi-final, Barcelona took an away goal advantage from their 1-0 victory at Bayern Munich as they seek to reach a maiden Champions League final.

Kheira Hamraoui's second-half strike was enough for the Catalans, who might have taken a bigger lead back to Spain for next Sunday's second leg were it not for some profligate finishing.

England forward Toni Duggan went close in the opening minutes before Hamraoui hit the bar and Vicky Losada saw a shot crash back off the post as they dominated in Bavaria.

Bayern responded before the break and almost scored against the run of play but were denied by a smart stop from Barca goalkeeper Sandra Panos.

Hamraoui's angled shot gave Barca the lead their play had deserved just after the hour and they clung on despite a late Bayern onslaught, with Sara Daebritz's stoppage time free-kick hitting the bar.
