Two individual errors have led to Arsenal's Women's Champions League title defence getting off to a losing start in a 2-1 defeat at home to eight-time winners Lyon.
Arsenal's Australian trio of Steph Catley, Caitlin Foord and Kyra Cooney-Cross all featured for the hosts, with Catley playing a full game at Meadow Park and fellow Matildas Foord and Cooney-Cross entering as second-half substitutes.
Gunners goalkeeper Daphne van Domselaar rushed her attempted pass out from the back and picked out Melchie Dumornay just outside her penalty area and the Champions League young player of the year for the last two seasons rolled the ball home at the second attempt.
