Real Madrid's unbeaten run under the returning José Mourinho came to an abrupt end on Friday, as a 1-0 defeat at Real Betis exposed the champions' vulnerabilities — and Kylian Mbappé's missed stoppage-time penalty ensured there would be no late escape.

Madrid created the chance to salvage a point deep into added time, but Mbappé's effort from the spot failed to find the net, leaving the Bernabéu side to absorb their first loss since Mourinho's return to the dugout.

Real Betis, playing at home, held firm throughout the contest to claim a memorable victory against one of European football's most decorated clubs.
