Real Madrid ace Cristiano Ronaldo was tightlipped about ref Gianluca Rocchi after their 1-1 draw at Manchester City.

Sergio Aguero levelled from the spot for City after Alvaro Arbeloa was sent off midway through the second-half.

"The images speak for themselves. I do not want to talk about whether the referee has been good or bad. Important thing is that we are qualified. I do not want to talk about the referee ... but he could be better," said Ronaldo.
