Juventus captain Gianluigi Buffon has said that he stands by the comments made about referee Michael Oliver following his side's dramatic aggregate defeat to Real Madrid.

The 40-year-old was shown a straight red card for dissent by Oliver after the English official awarded Madrid a stoppage-time penalty, which Cristiano Ronaldo converted to win the quarter-final tie.

Buffon was furious with both the penalty decision and the dismissal, telling reporters after the match that Oliver had 'a bag of rubbish for a heart'.

Juve legend Alessandro del Piero felt that the experienced keeper would regret the remarks, but Buffon is refusing to backtrack.

"The content remains and I stand by all of it," he is quoted as saying by BBC Sport. "I'd say them all again - maybe with a different type of language.

"You find a way to speak, right or wrong, that at times can seem excessive - but this is me, I am Gigi Buffon."

Juve had battled back from three goals down before Oliver pointed to the spot for Mehdi Benatia's foul on Lucas Vazquez in the 93rd minute.
