Wolves took a huge leap towards promotion to the Premier League in May after a dramatic win at Cardiff in April, in which the 'Bluebirds' missed two late penalties.
At the end of the game, Nuno celebrated wildly, prompting Cardiff boss Warnock to refuse to shake his hand later describe the Portuguese coach as a "total disgrace".
Ahead of Wolves' game at the Cardiff City Stadium on Friday, Nuno remarked to 'Sky Sports': "It is totally over. We had a chance to speak and we clarified things. Now I can say we are good friends.
"Both teams want the same so let's try to be better than them - but always with respect.
"It was a fantastic game last season. It was a very emotional game. Both teams know each other well, and we expect a tough game."
