Ahead of tonight's clash, Zenga was asked about Buffon's meltdown at Real Madrid last week.
"I am always pro Buffon, beyond the football faith," said the former Inter Milan keeper.
"You cannot criticise a person because he reacts and defends his fort ... Anyone at that moment would have reacted like that in a match like that and secondly against a club like that. I would have done even worse, certainly."
"We will fight to play our game."
