Arsenal battled back from a goal down to secure a 2-1 first leg advantage in their Women's Champions League semi-final against Lyon at Emirates Stadium.
The Gunners, who beat Lyon in the last four last season on their way to Champions league success, trailed following Jule Brand's 18th -minute strike.
However, Lyon capitulated after the break as an error from goalkeeper Christiane Endler led to Ingrid Engen's own goal before another late mix-up between Endler and Engen led to Olivia Smith scoring into an empty net to give the Gunners a prescious lead to take to France for next Saturday's second leg.

The loss is just Lyon's second defeat all season and their first defeat away at an English side in the Women's Champions League as Arsenal produced a huge result against the eight-times winners to continue their bid to retain the title they won last season.
