Derby boss Wayne Rooney has recalled losing his rag with former Manchester United teammates Paul Pogba and Jesse Lingard.
The trio shared a dressing room together during the 2016/17 season under Jose Mourinho.
Rooney wrote for The Times, "I do remember one time, coming into training at United the day after a defeat, still feeling very annoyed and walking into the dressing room with Michael Carrick.
"We found Jesse and Paul dancing in there with the music on. I went over, turned it off and took the speakers out of the dressing room — because that's my mindset, that's how I've grown up in football.
"Paul and Jesse accepted it, because I was the senior player, but in hindsight they were not doing anything wrong, not hurting anyone, and it was just my old-school mentality kicking in.
"As Rio Ferdinand has said, players of our generation just have to get used to this generation and what has changed."
