I know Roy Keane off-camera – he has three non-negotiables to get along with him

Just as he did when he was a player, Manchester United legend Roy Keane has certain expectations around the workplace.

That is according to his former team-mate Gary Neville, who has maintained a strong relationship with the Irishman thanks to their Sky Sports punditry gigs. And even now, it appears Keane is focused on driving standards and making demands of those around him if he's to play his part to the fullest.

Having garnered a reputation as one of Europe's all-time greatest hard men during his playing days, Keane is just as allergic to timewasting and laziness now as he ever was. And Neville provided some insight into his colleague's three must-have qualities during the latest episode of The Overlap on Sky.

"Ha! He can be a joker and has definitely got a good sense of humour, but he’s also very serious about certain things," said Neville when asked if any of Keane's cold exterior is an act. "He has his non-negotiables around work – he wants everyone to have the same attitude, application and pride in what you do – which I believe we all have.

"The Overlap is definitely where you see the real us – the raw, authentic us – more so than when we are commentating on football games. I think that’s one of The Overlap’s strong points.

"I always believe that when you get people together who are passionate about anything – whether it’s football or life or travel – and those people have a good relationship with one another, then you'll get good television. I think that's what The Overlap is."

Many viewers would agree The Overlap captures that, at least, giving even more input from some of the UK's favourite pundits each week. And Keane has continued his legacy as a screen favourite, providing a welcome, dry twist compared to his colleagues.

The 53-year-old is just as prickly as the player who once left the Republic of Ireland's World Cup camp after a fall-out with manager Mick McCarthy. That's not to say Keane isn't capable of showing his warmer side, however, which is perhaps why some are suspicious as to whether he's genuinely the tough guy persona he has long portrayed.

It should come as no surprise that even in his punditry responsibilities, the Cork man continues to make demands of those around him. And The Overlap (as well as his fellow pundits) is all the better for it.
