Arsenal took advantage of a catastrophic defensive error from Lyon to claim a crucial first-leg lead in their Women's Champions League semi-final. Lyon goalkeeper Christiane Endler collided with defender Ingrid Syrstad Engen, leaving the ball loose for Olivia Smith to tap into an empty net.
The mix-up occurred in the first half of the match, with Endler and Engen failing to communicate as they both attempted to clear a routine back-pass. Smith, alert to the opportunity, pounced to score the only goal of the game so far.
This is not the first time Lyon's defense has been caught out in a high-stakes match, and the error could prove costly as Arsenal look to reach the final. The second leg promises to be a tense affair.
