Lisbon: It was Juventus that prevailed over Porto in the first leg of their last 16 Champions League tie on Wednesday, a game that also marked a contest between goalkeeping legends Gianluigi Buffon and Iker Casillas.

Buffon emerged the winner over his Spanish rival, as strikes from Marko Pjaca and Dani Alves led Juventus to a fine victory. But the match will be remembered for something that occurred post final whistle.

Casillas and Buffon embraced each other in what was a wonderful gesture from the two goalkeepers. Rather than praising each other for being legends, Buffon spoke honestly about the match, Casillas said.

"Buffon told me that the red card (to Porto left-back Alex Telles) made it easier for Juve," he said. "He's a great competitor... A class apart," Casillas added.

Talking about the match, Casillas rued the red card which he believes changed the complexion of the game. "We tried to do well, but those two minutes really changed everything. We could've fought it out with Juve otherwise.

"It'll be better for us in the second leg if they have someone sent off early on, but either way we need to work hard and keep believing. It will be difficult, but we will give it our best in Turin," Casillas stressed.

For the past 20 years, Buffon and Casillas have battled with each other for the best goalkeeper's award.
