"He has come to terms with it," said Calzaghe. "There's no one to blame but himself. He won't do that again.
"A defeat doesn't have to be the end, it could be the beginning of your life. He wasn't hurt technically.
"I'd rather it have gone that way than him been involved in a 12-round war. There is no physical damage like there would have been in a long battle. The only thing hurt is his pride.
"All this said, Haye did nothing for me to change my views on him. It wasn't his performance that counted it was Enzo's performance. He was only as good as Enzo made him look.
"He answered no questions to me. He only threw four punches himself a round. Four whole punches.
"You can't judge what Haye is all about from that fight. It took him five big straight rights to deck Enzo.
"Now you think he is going to be fighting 17-stone guys [by moving up to heavyweight division]. It will take a lot more to put them down."
"He won fair and square but let's not get carried away because Enzo underperformed."
Calzaghe said there could be lots of reasons why Maccarinelli lost the fight but backed him to bounce back.
"It wont be hard to get Enzo over this," said Calzaghe. "He's a very positive character.
"He believes in his ability and he won't blame anyone. He knows a true Enzo would have done a job on this guy.
"He will be back. He had a bad turn, he's licked his wounds and he'll come back harder, stronger and better... and we'll be ready to rumble with Enzo again.
"We'll give him a 10-rounder to start with to dust the cobwebs off and then we'll get him straight back fighting for a world title."
