Wolves head coach Nuno Espirito Santo insists he has learned his lesson after his heated exchange with Cardiff boss Neil Warnock last season.
Warnock repeatedly used expletives towards Espirito Santo and then later called him "a disgrace" in his post-match press conference, after the Portuguese had run on to the pitch to celebrate Wolves' dramatic away win against their Championship title rivals instead of shaking Warnock's hand.
Ahead of the first meeting between the two clubs since that game in April, Nuno said: "I respect him. What happened was clarified and we had a chance to speak, not only by phone but personally.
"We also spoke at the LMA awards and had a good moment. Things are clear, I respect him a lot and we are going to compete tomorrow. I am going to shake his hand, before and after. I have learned my lesson.
"It's the past. I understood in that moment how Neil reacted and I apologised and I will not repeat it again."
