Roy Keane always has said he took more from Brian Clough than he did from Sir Alex Ferguson.
And now it seems he has taken that rather literally, after police and an ambulance were called to the Republic of Ireland team hotel after a disagreement between Keane and a fan over the country's assistant manager.
A witness told the Irish Mirror: "One guy was reading Roy’s book and wanted him to sign it. I think Roy told him no and then there were words exchanged. It all just kicked off from there. There was lots of roaring and shouting after.
"An ambulance was called and your man was taken away. The players were coming in and out of the bar before and then they were called in to a private room.
"Everybody in the bar is talking about it. You don’t see something like that every day."
The FAI have since clarified that it was Keane himself that called the Gardai, but this presents us with an excellent opportunity to remind ourselves of a particularly famous incident involving Clough from 1989, when he took justice into his own hands following a pitch invasion at the City Ground.
Of course, the brilliant post-script to the story was that Clough, after punching two fans in the head, got both to apologise to him, on TV, giving them the traditional Clough kiss in the process. It also led to the famous apocryphal newspaper headline 'The Shit Hits The Fan.'Roy Keane taking more and more inspiration from Brian Clough
Here's a reminder of what Keane said about Clough in his latest autobiography:
'I worked under two great managers and I put Brian Clough ahead of Alex Ferguson for a simple reason. What was the most important thing in my football career? Brian Clough signing me. That kick started everything,' he writes.
'Different managers, both brilliant. I think Clough’s warmth was genuine. I think with Sir Alex Ferguson it was pure business – everything is business. If he was being nice I would think: ‘This is business, this’.
'He was driven and ruthless. That lack of warmth was his strength. United was a much bigger club than Forest but his coldness made him successful.
'His message was the same. I was never once confused by one of his team talks or his tactics or his training. The message was always fresh. I must have heard him talk 500 times and I always thought: ‘Yeah, that was good’.
'I think that’s amazing. As a manager I would take Clough’s warmth and Ferguson’s ruthlessness and put them in the mix – but also add my own traits.'
