Roy Keane was left 'raging' after his phone went off during the latest episode of Stick to Football, much to the amusement of his co-hosts. 

The former Man United captain, who famously once snapped at a journalist for failing to put his mobile on silent during a press conference, ironically interrupted this week's guest Ashley Cole. 

'We had the odd opportunity to come and train,' the former Chelsea defender was explaining when cries rang out around the studio as Keane's phone started ringing. 

'That's Stick to Football history,' an ecstatic Gary Neville joked. 'The ill-discipline!'

Keane, shaking his head with embarrassment, replied: 'I'm raging with that. That  breaks me. My phone's always on silent!' 

Recalling the famous press conference when he urged a journalist to 'turn his phone off' while he was Ipswich Town manager, the 54-year-old added: 'I did an Ipswich game last year for Sky and the guy whose phone was ringing came over and apologised to me. 

'I asked him, "why didn't you switch it off all those years ago?", he came back and said, "I was nervous, I didn't know what to do." But yeah, he apologised.' 

Keane's phone-related blunder comes just days after he was sensationally tipped for the Man United job by his former team-mates Nicky Butt and Paul Scholes. 

Speaking on his The Good, The Bad and The Football podcast with comedian Paddy McGuinness, Butt admitted he 'can't fathom' the fact that United have never reached out to Keane about the possibility of taking over the club, even on an interim basis. 

The Red Devils have employed an array of managers since the great Sir Alex Ferguson's departure with David Moyes, Jose Mourinho and Louis van Gaal amongst the bosses who have tried and failed to bring success back to Old Trafford.

Yet for Butt, the man who could turn United's fortunes around might be right on the club's doorstep. 

'Do you know what I can't get my head around,' the former England midfielder began. 'Why Roy Keane has never got a chance at Man United. 

'I know he's a mate, so it's a bit biased, but if you look at his personality and his playing career there, his character, and what he did in his managerial career - he did unbelievably for Sunderland. 

'If you look at all the troubles they've had, and he still lives locally, I can't for the life of me fathom how nobody has sat down with him and had a conversation and said, "would you be interested in the job?"

'Even as an assistant. You look what he did with Martin O'Neil, you could've given David Moyes a Roy. I just think when it's been going bad, if they'd got Roy in, Roy is a very astute person, he's a very clever bloke. He'd then go and get a really good coach in to do the stuff that he might think he's not the best at, because I think Roy is very much a Sir Alex Ferguson manager.

'He's a manager, he manages people. He comes alive on match days. He tells people what to do, he looks at it. He’d go and get some, whatever his flaws, he’s not too big to think, well I need this and I need that and I’ll go and get it.' 

Keane has been out of management since leaving his role as an assistant coach of the Republic of Ireland national team in November 2018. 

Before that he'd enjoyed stints as head coach of Ipswich Town and Sunderland, who he helped to the Premier League in 2007.
