Great Britain (GB) suffered a heartbreaking extra-time defeat in the Olympic women’s football quarter-finals as Chelsea’s Sam Kerr dealt the final blow to give Australia a dramatic victory. In a frantic encounter, GB’s Ellen White scored a hat-trick, while Manchester City team-mate Caroline Weir had a penalty saved in extra time before Australia scored twice. Kerr’s 89th-minute equaliser had forced extra time before Australia teenager Mary Fowler’s heavily deflected strike crushed GB’s momentum after Weir’s penalty miss. Hege Riise’s side were rocked when Kerr rose above GB captain Steph Houghton to head in a fourth for Australia, but White responded to set up a nail-biting finale.
