Leave it to Cristiano Ronaldo to come through when Real Madrid needed him most. After going down a man only a few minutes earlier when Sergio Ramos was shown a second yellow card, Madrid got a chance to counter-attack. Gareth Bale got it on the wing and sent in a looping cross to Ronaldo at the far post. Dani Alves somewhat mistimed his jump, Ronaldo deftly controlled it off his chest and then did what he's best at, finishing.
Ronaldo may not be having a season that is up to his normal standards, but this is about as big as goals get.
