Football is seen as a tribal sport. You are born supporting a team, be it the one down the road from your house or the one your parent forces you to cheer for on a Saturday afternoon.

Regardless of the reason, you swear blind loyalty to that team and want them to be successful over all the rest. Or so I thought.

Leicester’s Premier League triumph has flipped that narrative on its head. Supporters of rival teams have willed them to the finish line and have celebrated with them over the past few months. 

As the Foxes have travelled around the 19 Premier League teams, they have been greeted with messages of goodwill and after they have left the stadium with three points, they have been clapped by the whole stadium. This isn’t meant to happen.

It’s been fascinating watching the whole of football unite behind one team. Arsenal and Chelsea fans supporting Leicester, furious with their own teams’ failings but pleased for someone else to do well.

Had it been either of the Manchester clubs running away with the title as it has been over the past few years, there would have been no way the rest of the world would have been chanting: “Glory Glory Man United.” It would be unheard of.

I’m not old enough to remember the inaugural Premier League season, as Alex Ferguson and the Class of 92 went on to win United’s first title in 26 years.

But I highly doubt rival fans wanted them to win the league. It could be argued that the Red Devils had a history of success so their “fairytale” story of winning with local kids wasn’t as glamorous as Leicester’s.

Blackburn’s title win in 1995 is the closest I can think of an “underdog” story. They obviously spent money to win the league but no-one expected them to actually go all the way. 

But judging from the media coverage over the past few weeks, it wasn’t that much of a surprise.

I am old enough to remember Liverpool a few years ago and their close run-in with the Premier League title.

Again, maybe because they are a team steeped in success and are among the Premier League elite that people were delighted when Steven Gerrard slipped and ruined their chance of claiming the team’s first Premier League title.

But they were that season’s underdog, if you could call them that. 

The reaction of Tottenham fans the morning after has been the most baffling to me. After the 2-2 draw with Chelsea, I noticed plenty of congratulations tweets from their fans.

Maybe it was because deep down they knew the title was over and were clinging on to a small miracle.

But sportsmanship in football is a concept I am not used to. Before this season, I didn’t think it existed.

It is like the episode of Friends when Joey fails to win a Soapy. The camera pans to him and he is clearly furious at the fact that he lost but when he realises the world is watching, he claps and acts gracious.

Was that how Spurs fans were behaving? Putting on a happy front on social media but crying and trashing their rooms in private?

Personally, I hope that is their reaction. Not to be bitter but because it would bring a sense of order to what has been a whirlwind season.

The tribalism came to the forefront of the sport on Monday night when Chelsea met Tottenham at Stamford Bridge and did all that they could to make sure they lost the league that night.

The atmosphere in the ground was hostile and the battle lines were drawn. 

Some Chelsea fans rightfully asked where that passion from their side was for the previous 30-plus games and had they cared as much about retaining their title as they did about stopping Tottenham from winning one, they may have had a better season.

But there was still overall happiness that a club managed by their former boss had achieved what they had set out to do at the start of the season.

It would be interesting to see how supporters react to Leicester becoming a new force in the Premier League, if they were to kick-on from this season and go on to dominate over the next decade.

Will the rest of the league be as supportive? Would fans of Arsenal and Chelsea next season be supporting the Foxes if they are unable to mount a serious challenge?

The most common answer I got when posing this scenario to people was that they couldn’t see Leicester sustaining it. 

When whether it’s a case of not being able to see and not wanting to see, the conversation has stopped there.

Like they know that they would have to hate everyone’s new second team.

It is the hipster thing to support Leicester this season but only on a one-off occasion and there is nothing wrong with that.

Europe fell in love with Jurgen Klopp’s Borussia Dortmund on the road to their Champions League heartache in 2013.

The story of the plucky underdog conquering the mighty, David beating Goliath, Jeremy Corbyn becoming Labour leader, are the ones that people love to fall in love with.

But the moment they overstay their welcome, that is when they should know their place and get back to where they belong.

City and Chelsea were at some point the little man until they were funded by sheikhs and a Russian oligarch respectively to take a permanent seat at the high table.

Leicester already have a sugar daddy funding them lest we forget, just not to the extent of other clubs that have dominated English football.

But the money is there to make this a regular occurrence. And given the TV deal, Leicester can easily build a footballing powerhouse to now challenge Europe after conquering England.

How supporters accept a new team at the dinner table is something I am very interested in finding out about.
