GAA pundit Joe Brolly believes Roy Keane has "all sorts of deep-seated psychological issues" that have never been dealt with.
The assistant manager of the Republic of Ireland team hit the headlines last week following a fracas in the team hotel in Portmarnock ahead of their defeat to Scotland in the Euro 2016 qualifiers.
Gardai were called to the scene after a man who claims to be a long-term friend of Keane's - Frank Gillespie - claimed that he was pushed by Keane.
The FAI subsequently sent out a press release playing down the incident and expressing their full support for Keane.
Former Derry star Brolly said that Keane (inset) was the football equivalent of the 'Kardashians'.
"Keane is just, you know he is interesting and for the media it is fantastic, it's like having a soccer coaching Kardashian," said Brolly.
"I think that O'Neill enjoys him more than anything else. O'Neill has got broad shoulders and O'Neill is smart.
"Keane brings huge interest wherever he goes but I think he will fail wherever he goes as a manager because he doesn't have any of the emotional intelligence that is required," he added.
"I would imagine that he has all sorts of deep-seeded psychological issues that have never been dealt with.
"As a soccer player, he was just a freelance soccer player, all he had to do was play soccer and he was brilliant at that of course and he burned so brightly. But then he reaches the age of 35 and because he has never had to change or think about himself, he has never done that and his personality is absolutely set in stone."
"If you've got Roy Keane, it's a bit of fun, it's showbiz and all of that."
Brolly was speaking on Off The Ball to host Joe Molloy and said that Keane regularly reacts to confrontation.
"His towering rages, the way be behaves, the constant craving for publicity.
I must say I feel sorry for the fella," he said.
