Roy Keane is no stranger to falling out with people in the world of football.
The Irishman often became involved with opponents, managers, and teammates over the course of his lengthy career. Some of those incidents have been more high profile than others, although we have now learned of a new one.
It involves Keane and one of the high profile former referees in football, although this one seemed to be fairly one-sided.

Gary Neville reveals Roy Keane feud with former referee
Mark Clattenburg is a controversial figure at the moment, with questions being asked about the former Premier League referee's current role at Nottingham Forest.
While many have questioned his conduct in recent times, it seems that Roy Keane's issues with the 29-year old stretch back even further.
Speaking on Stick To Football, brought to you by Sky Bet, Gary Neville revealed an awkward encounter he and Keane had with Clattenburg at the 2022 FIFA World Cup.
He's your mate Clattenburg! You were all over him at the World Cup.
So basically, we're walking along this place in the World Cup, the three of us were having a chat and Mark Clattenburg walks towards us.
Right, he's worked with us at the previous World Cups as our refereeing consultant, we trained with him and got to know him a bit.
So basically, we're walking along and I'm like 'Hi Mark, how are you?' and then Wrighty goes 'Mark, good to see you!' and then he [Keane] hangs back a few yards.
And then he goes over to Roy to shake his hand and Roy goes [makes aggressive handshake motion]. No word of a lie!
He threw his hand away! And I'm like, 'What's going on here?! I know he's a bit feisty but...'. You [Keane] carried on walking and we were left talking to him and I said, 'Ref, is there a problem?'.
Considering that the pair had previously worked alongside Clattenburg, Neville certainly seemed to be surprised by the Cork man's behaviour.
However, Keane would go on to explain why he gave him the cold shoulder on this occasion:
He'd said something in a book after he worked with us.
Roy Keane would go on to admit that he doesn't actually remember what the comments in question were.
Still, this is incredibly on brand.
