The case against Manchester City is unprecedented.

The Premier League champions are facing the threat of being banned from the Champions League after being accused of breaking Financial Fair Play rules.

The allegations put a slight stain on Pep Guardiola’s historic team.

Is there anything impressive about succeeding only after breaching the rules?

UEFA are investigating the matter, with City protesting their innocence.

But regardless of whether they are found guilty, their actions have already upset La Liga president Javier Tebas.

Tebas has launched an astonishing attack on the Manchester club, accusing them of ‘ruining the entire system’.

Tebas: Man City should be banned

City's billionaire owner Sheikh Mansour has spent lavishly since his arrival in 2008, putting more than £1.3 billion into the club.

And Tebas would not be averse to City being kicked out of Europe.

“If we allow that money comes in that isn’t generated by the industry itself, and it’s money coming from states, this is no longer sport. This is no longer an industry,” Tebas said, per the Mirror.

“It becomes more like the toy, the play thing of a state. And when it’s a play thing, kids start playing with other kids. You end up ruining the entire system.

“This is what PSG, Man City or clubs with lots of money can put the entire industry at risk which is what really UEFA should have been working on.

“Because the origin of this entire problem is the inflationary effect that Man City and PSG have created across the whole of Europe and the rest of the clubs in Europe want money to compete with these guys.

“I don’t know what sanctions will fall upon Manchester City but I would not be surprised by any sanction.

“If it was based upon what we have already denounced publicly then we think it should be (a ban), just as PSG should also be outside of European competitions.”

City’s spending - Guardiola has spent £547.28m on players since joining in 2016, per transfermarkt.com - could be about to catch up to them.
