The pair are among the most combustible managers in the top flight, and the prospect of the two of them prowling the touchline has piqued interest ahead of tonight’s Selhurst Park showdown.
However, Di Canio believes that Holloway’s abilities as a football manager are often overlooked in favour of discussions about his out-spoken nature. He feels the Palace boss has “knowledge” that should not be under-estimated.
He said: “In my opinion, some people under-estimate the real value of the man. When you move to the dugout, you have a different expression, a different vocabulary.
“He’s done fantastically at the clubs he’s managed, but people forget that because if they’ve gone down, that’s all they remember.
“But it’s not easy to stay up.
“He’s got good tactical skills, but people don’t look at this because of his public expression. That is not fair.
“I know that from your point of view, there is curiosity (about their respective perceived craziness) but for me it’s not important.
“I like him, I like his passion and it’s clear that he’s got tactical skill. He’s got knowledge. But I hope I can beat him, that my team can beat his team.”
