LaLiga president Javier Tebas has launched a furious attack on Manchester City and their transfer spending.
Tebas insists City must be banned from the Champions League with the reigning Premier League champions accused of breaking Financial Fair Play rules.
Tebas says City's billionaire owner Sheikh Mansour has effectively made European football an unfair playing field with UEFA last week confirming they are considering potential punishment.
He said: “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.
“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."
Tebas says he spoke out on City in 2016 and they threatened to take legal action against him - but that has never been forthcoming.
Tebas added: “Manchester City during SoccerEx two years ago, I said they weren't living up to FFP standards. City sent me faxes and legal documents saying they were going to put me in front of a court in Manchester if I didn't correct my statements.
“I still haven't gone to court in Manchester, nor have I been called to present myself there. So I reaffirm what I said on that day. What's surprising is that it's taken so long to come to light. It's been happening for a while."
