Real Madrid extended their lead at the top of La Liga to seven points thanks to a late win against Athletic Bilbao.
Athletic's San Mames is one of the toughest away trips in Spain and Real faced another gruelling match even without any fans in the stadium, as the Basques continually closed them down and subjected them to their usual aerial bombardment.
But Sergio Ramos scored from the penalty spot in the 73rd minute after Marcelo had been fouled.

Athletic goalkeeper Unai Simon attempted to distract Ramos but the veteran defender maintained his composure to seal the important victory while scoring a 22nd consecutive penalty for club and country and move into double figures for goals this season.
That result not only strengthened Madrid's position at the top of the table but continued their perfect start since returning from lockdown.
