Once upon a time, football fans used to come home from seeing their side lose, and they would shrug their shoulders, kick the cat or get roaring drunk.

But now, a new generation of self-obsessed morons are taking out their angst by switching on a video camera, putting on the latest multi-sponsored £100 football shirt of their team and, literally, screaming into the microphone. Welcome to the world of fake outrage spouted by, predominantly, young and often photogenic YouTubers and vloggers.

Unsurprisingly, it is the ‘big’ clubs that attract the most prominent of this new breed: mostly Manchester United, Chelsea and Arsenal.

After United lost 4-3 away to Bayern Munich this week, one video had a young woman shrieking ‘I’m sick of this club’ in a performance worthy of a soap opera. One of Liverpool’s myriad fan channels, The Redmen, posed the question: ‘Should Doak start over Salah’ in what surely must be a wind-up.

Then there’s a Chelsea YouTuber who looks like he wasn’t born before Roman Abramovich ‘founded’ the club in 2003. He has a video in which he explains to the manager, Mauricio Pochettino – who has managed in three countries and taken a side to the Champions League final – exactly what he’s doing wrong. Judging by the accents, a lot of these rants do not appear to come from the cities of the clubs they support: more likely to come from Chenai than Chelsea.

There does not seem to be a plethora of feigned filmed outrage for money from supporters of Tranmere Rovers, or clips of four or five Newport County fans filming themselves in their living room watching a game on TV, so that everyone can see their overacting responses to a misplaced pass or conceded corner. However, there are hundreds of examples of these among those following the biggest clubs, often by those who think football was invented in 1992 when the Premier League was formed.

Feigning anger for money is now a major side hustle for today’s young fans who, within seconds of the final whistle, will launch a video clip on YouTube or Twitter where they will shout ‘I’m sick of this club’ or ‘sack’ the manager.

Sadly, it works. These accounts appear to have followers in their thousands and even hundreds of thousands. Ranting pays more than reason. It’s a tactic shock-jock radio stations have learned too, with much-shared clips of fuming phone calls to the likes of TalkSport and the BBC’s 606 show, both of which appear to rely on former second-rate footballers who are now third-rate broadcasters to stoke the flames of supporter’s anger.

It was on TalkSport that former Spurs under-performer Jamie O’Hara actually uttered the immortal rhetorical question: ‘Was Harry Kane holding Spurs back?’ That’s the club’s record goalscorer he’s talking about remember.

Every caller, often using meaningless statistics about a team’s xG (expected goals) think they know more than the coach about tactics, formation and team selection.

If fans are spouting nonsense, then it’s no surprise that the genuine ‘pundits’ are behaving badly. No afternoon on Sky Sports seems complete without any two or more of Micah Richards, Gary Neville, Jamies Carragher and Redknapp, or Roy Keane having a bust-up. There was a furious argument between Redknapp and Neville after Brentford beat Manchester United 4-0 a while back, ranting about what should be done to put United back on form (as if they have a God-given right not to lose to well-organised teams such as Brentford.) Like schoolboys in the playground, neither would let the other finish a sentence. If this is meant to be expert analysis, then give me Michael Owen with such pearls of wisdom as ‘when they don’t score, they hardly ever win.’

But perhaps the jewel in the crown of fake outrage is the YouTube channel Angry Rantman. At least it does what it says on the tin. This, for example, is his reaction to Chelsea losing 6-0 to Manchester City a few years ago:

Getting angry or upset over one’s football team is, of course, nothing new. Tell me about it… I support Spurs. But I and the miserabilists I have stood and sat with for more than four decades do not feel the need to video ourselves watching matches, have our own YouTube channels or have nonsensical nom de plumes to create our own ‘brand’. We probably wouldn’t know how. Instead we have a moan over a pint, talk about being Spursy and then renew our season tickets every year.

But then we are what are now termed ‘legacy supporters’ – a description that suggests the club have inherited us from a previous era rather than lured us in with targeted marketing. It suggests we’re going to turn up waving rattles and wearing flat caps (though it’s good to see West Ham fans have unwittingly kept that tradition alive).

We are made to feel we are not the lifeblood of the team any more though by passing on our loyalty to the next generation probably has some value.

Anyone who supports a ‘big team’ should be grateful they are not fighting for their very survival. Moan all you like about Levy, the Glazers or some Middle East despot owning your club for sportswashing. I get the expectation but ditch the entitlement and be thankful you are not facing eviction from your ground or a winding up order.

There are things worth being angry about – big name clubs wanting to form a European Super League, soaring ticket prices, owners with dodgy human rights records, Jamie Redknapp’s punditry, a new kit being launched every season, VAR decisions and inconsistent referees, 13 minutes of injury time, the last train home scheduled to leave half an hour before the game ends and, of course, half and half scarves.

Losing a match, keeping Eric Dier on the payroll or having a lower xG rating than Manchester City are not.
