Sam Kerr knocks pitch invader to ground during Champions League match

In the closing stages of the group stage game, the man entered the field and briefly held up play before he was sent sprawling as the Australia captain dropped her shoulder and ran into him.

The boos that had greeted the invader instantly turned to cheers for Kerr, before the man took to his feet and made his way from the pitch with stewards in pursuit, to applause from the stands.

It capped a frustrating night for Chelsea, who failed to score for the first time this season as they were held to a goalless draw.

In the 1982 Ashes Test in Perth the Australian bowler Terry Alderman dislocated his shoulder after tackling one of a group of spectators who came onto the field.
