Alex McLeish has insisted “everybody” has got the wrong impression of Roy Keane amid talks over taking charge at Celtic. 

The former Scotland manager, speaking exclusively to Football Insider, suggested the 49-year-old was a different character behind closed doors compared to his public persona.

As revealed by Football Insider, Keane was interviewed by the Hoops last week and is keen to succeed Neil Lennon.

Former Manchester United teammate Nicky Butt has been lined up as his assistant manager after stepping away from Old Trafford last month.

Keane, who started out in management at Sunderland, has not been a head coach since leaving Ipswich Town in 2011.

However, he has been an assistant manager with the Republic of Ireland, Aston Villa and Nottingham Forest.

He has since established himself as a high-profile pundit for the likes of Sky Sports.

Keane’s no-nonsense analysis and emotionally-driven commentary have made him a popular addition to the media world.

However, McLeish has insisted Keane puts on a persona for television and that he is actually a highly intelligent and analytical individual off-screen.

As such, he suggested Keane and Roy could be a great appointment for the Bhoys.

“It seems a good partnership,” McLeish told Football Insider assistant editor Russell Edge.

“Martin O’Neill speaks highly of Roy. He has worked closer with him than anybody. I know Roy personally and I found him a captivating character.

“He defies what everybody else kind of thinks.

“He has a super-intelligent footballing mind. I don’t think he’ll stop being grumpy but when I meet him in private life, I don’t see him being grumpy. 

“I think Roy and guys like that have a persona. They will do what they think is right and that’s the way you have to do it.”
