Fede Valverde's superb 93rd minute strike kept Real Madrid on Barcelona's tail in the Spanish title race, earning the champions a 1-0 win over Athletic Bilbao on Sunday. 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.
