Valverde stunner saves Real Madrid title hopes against Bilbao
Madrid stayed four points behind Barca after Valverde smashed into the top corner with a sliced, swerving effort.
After Champions League elimination by Arsenal it looked like Madrid were set for another devastating result until the Uruguay international's stoppage-time intervention.
"Fede has such a good shot... in training yesterday he shot a ball that looked like it was going out and then it picked up a curl like that and you go 'how do you shoot like that?'" said Madrid goalkeeper Thibaut Courtois.
