Former Manchester United defender Gerard Pique has lifted the lid on Roy Keane final years at the club.
Sir Alex Ferguson and Roy Keane's parting of ways has been dug up recently by the former United manager's autobiography, which saw his former captain hit back at him as disloyal.
Ferguson said that when Keane started criticising younger players in the squad, he had to go for he was having a negative impact in the dressing room.
One now world class defender who was a United youngster at the time was Gerard Pique, who signed for the club in 2004, 14 months before Keane unceremoniously departed.
Speaking with Spanish magazine 'So Foot' recounted by Marca, the Barcelona defender, 26, has been recalling a 'terrifying' experience he had with the club captain in his early days at Old Trafford.
"He was a player that instilled you with fear. I remember being in the Manchester United dressing room one day prior to a game.
"I had just hung my trousers up when my mobile started to vibrate in one of the pockets. I immediately stopped it, and it hadn't even made any noise, it just vibrated.
"But he went absolutely crazy, shouting 'What the f***!'. He was screaming at the top of his voice. He was terrifying."
Keane's hard line approach was clearly too much for Ferguson in the end, but a player who demanded high standards and professionalism in all walks of his football life.
There's a clear message for Republic of Ireland internationals here, where Keane has just become assistant to new boss Martin O'Neill: Turn your phones off...
