Why penalty for Williamson handball was correct call

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.
