A bizarre error from Arsenal defender Leah Williamson proved costly in their 2-2 draw with Paris FC on Wednesday in the Women's Champions League.

With the Gunners leading 2-1 late on, England captain Williamson stopped a short goal-kick with her hand - believing it had not been taken and that she was to take it - resulting in a penalty being awarded to the hosts, converted by Maeline Mendy.

The unusual incident means the Gunners are fourth in the Champions League table after their opening two games, but would have been second with a victory in the French capital.

After the ball had gone out of play for a goal-kick, Arsenal goalkeeper Misa Rodriguez played a quick, short pass to Williamson.

Williamson had her arm stretched out to stop the ball and place it so that she could take the goal-kick herself.

With the ball being still and on the field of play when Rodriguez played the ball to Williamson, that was deemed to be the goal-kick instead of Williamson's attempt.

Therefore Williamson was penalised for handball and Mendy levelled the match from the penalty spot.

While Arsenal felt aggrieved at the decision, the guidance on such incidents state that the decision to award a penalty was correct.
