Manchester United legend Paul Scholes has revealed that former manager Sir Alex Ferguson went ballistic at one player for posting a dressing room picture on social media.
Writing in his column for the Independent, the former United midfielder, who retired from the game at the end of the Ferguson era in 2013, has insisted that the dressing room he was involved in was a place of privacy.
The issue, of course, has been raised in recent weeks, with Arsenal stars often posting pictures after certain matches on Twitter and Instagram.
And Scholes has suggested that Arsenal stars should only take photos after securing trophies - not after beating the likes of Manchester City at the Etihad.
The Manchester United hero wrote: "It was Aaron Ramsey doing it on Sunday after Arsenal beat Manchester City 2-0 at the Etihad Stadium, although I am told he is by no means the only offender.
"In my world the dressing room was sacrosanct. The only time anyone was permitted to take pictures in there was when we had won a trophy. Unless I am wrong, Arsenal only got three points for beating City. It wasn't the European Cup final.
"In my final couple of years at United we had one player, new to the team and young, who posted a picture from the dressing room on Instagram or Twitter.
"I won't embarrass him by naming him because that too would contradict the rules about what stays private. Safe to say, the manager went ballistic and the player never did it again."
There's no doubt about it, the 'selfie' debate has certainly split opinion in the footballing community, but it looks set to rumble on as social media continues to thrive in the modern game.
Scholes, meanwhile, certainly won't be expecting any of his former teammates take any pictures at Abbey Road this evening as the Red Devils take on Cambridge United in the FA Cup fourth round.
Arsenal, meanwhile, will also be in action this weekend as they travel to Championship outfit Brighton on Sunday. Both United and Arsenal will no doubt be hoping to win the competition, and perhaps even take a 'selfie' at Wembley in May.
