Real Madrid ace Cristiano Ronaldo was delighted to prove the matchwinner in victory at Rayo Vallecano.

Ronaldo struck with an audacious back heel to be the difference.

"Rayo played a great game and made things very difficult for us. They had chances to draw the match, but we defended well and earned a favourable score," said Ronaldo.

"It was a messy game, especially in the opening minutes, because neither team had control of it. The coach spoke to us during half-time and we concentrated harder. We're very proud of the job we did because these three points will help us win the title.

"I didn't even think when I scored. I just hit the ball with my heel and therefore surprised the defenders and the goalkeeper. I hit it strongly enough so they couldn't stop it. It gave us the victory, so it's worth twice us much to us.

"We shouldn't focus on what others do so long as we do our job right."
