With the game poised at 1-1 following goals from Adrian for the visitors and Nacho for the hosts, it looked like the two sides would be going in level at the break.
Step forward Gareth Bale. The Welshman demonstrated his ability to produce something out of nothing when he gathered Marcelo's cross from the left at the far post just three minutes before half-time.
The 'Cardiff Express' cut inside onto his favoured left foot, before curling a sensational strike past Ruben in the visiting goal and into the top corner, with a kiss off the post for good measure.
It was a sensational strike form the former Spurs man, who already has five La Liga goals to his name this season despite his limited game time.
