It's safe to say that Roy Keane is quite an intense bloke.
The former Manchester United captain never shied away from a 50/50 tackle as a player and certainly doesn't hold back his opinions as a pundit now he's retired.
In particularly, Keane seems to get most worked up about (apart from prawn sandwiches and the topic of Sir Alex Ferguson) is the growing phenomenon of players taking pictures of for social media celebrating after matches.
In an interview with Newstalk, as quoted by the Mail, Keane famously took aim at the selfie-obsessed generation.
"I see players nowadays, they get a result and they're taking selfies or swapping jerseys at half-time... they're almost enjoying it too much," he said.
"If you're playing for a big club and you get a result, of course enjoy it. But you have to move on pretty quickly and get ready for the next battle. Because this game, it can beat you up."
The ex-Republic of Ireland boss said recently of Arsene Wenger's Gunners: "'There's too many Arsenal players interested in selfies, I think, whatever they are.
"Instead of focusing on winning Premier League titles, it's all about how their bodies look, how their hair is, more so than winning football matches, which is the way things are going.
"They've got good players, really good players, it's just one or two of their players are more interested in selfies and six-packs."
All sage advice from Keano. However, ex-United teammate Rio Ferdinand may have just blown the no nonsense midfielder's cover as a secret selfie lover, after posting a throwback picture to twitter.
The former England defender uploaded an image of himself and Ruud van Nistelrooy shamelessly having their photograph taken by none other than a slightly hypocritical and smiling Roy 'No Selfies' Keane.
I guess technically that wasn't a selfie but does this hint at a gentler, more open, almost Kardashian-esque side of Roy? No, almost certainly not.
