As two of the most iconic players in the early days of the Premier League, it is no surprise that Alan Shearer and Roy Keane.
The most infamous example came in 2001, with the Manchester United captain being sent off for lashing out at the Newcastle forward.
It is certainly one of the most well-known examples of Keane's short fuse on the pitch, but the man at the other end of that incident has revealed that it didn't end there.
Writing in his column for The Athletic, Alan Shearer has revealed that Keane was waiting for him in the St. James' Park tunnel at the end of the game. However, it did not elevate to a physical altercation due to the intervention of their teammates.
Towards the end of Newcastle’s dramatic 4-3 victory over Manchester United and in a moment of frustration, Roy threw the ball at me, there was a delicate, polite conversation (OK, it wasn’t either of those things), he took a swing and missed and was then shown the red card.
When you went from the pitch into the tunnel at St James’, there were a set of steps and then you split towards the home or away dressing-rooms. When the final whistle went, Roy was standing at the top of the stairs waiting for me.
I’m pretty sure a few more choice words exchanged, there was some bustling and scrambling, but there were way too many people between us for anything physical to actually happen. That’s usually how it pans out in football.
Roy was never an enemy, that’s definitely not the right word but when you want to win as much as we did, things would occasionally spill over.
We’ve worked together on television over the years and there’s never been any problem. We’ve got on well. And what a competitor and player he was.
Keane certainly wasn't averse to confronting opponents, teammates, or managers over the years. We're sure you can think of a couple of well-known examples...
