Cristiano Ronaldo shows his frustration after yet another Barca goal

Though Real Madrid looked as if they might turn things around early in the second leg of their Copa del Rey quarterfinal against Barcelona, it was Barca who scored first (and second) to add to their lead. Lionel Messi slipped a pass to a wide open Pedro as the Real defenders converged on him, setting up a relatively easy goal.

Even as an observer, it felt like a crushing moment for Real -- a theory that Cristiano Ronaldo confirmed with his stompy show of frustration in response to the goal.

Then, just two minutes later, Dani Alves made it a 4-1 lead on aggregate with this absolute blast into the far corner of Iker Casillas' net...

Alves and Eric Abidal do need to work on that "Ai Se Eu Te Pego" dance, though.
