LaLiga president Javier Tebas believes the majority of Premier League clubs are of the opinion that Manchester City should be punished over their 115 charges.
The hearing into Manchester City's 115 alleged breaches of Premier League financial rules will begin on Monday.
City have been accused of financial impropriety spanning nine years from 2009 and the sternest punishment if found guilty is relegation. Points deductions and fines are also potential penalties.
The League charged City with a failure to provide accurate financial information and a failure to provide accurate details for player and manager payments.
An investigation was sparked by Der Spiegel publishing Football Leaks documents in 2018 and City stand accused of funnelling money from the club's owners through sponsors in the United Arab Emirates.
City — who declined to comment — deny wrongdoing and are defending their case at an independent inquiry.
Tebas has been a vocal critic of City and their spending model for years and he has once again taken a swipe at the English champions.
'I have spoken with many Premier League clubs and most of them understand that City should be sanctioned,' he is quoted as saying by Mundo Deportivo.
He added that 'they were once acquitted by the CAS [Court of Arbitration for Sport] for a formal matter,' hinting that the reversal of the UEFA ban was only on a technicality.
Javier Tebas also spoke about the Premier League, saying that 'this year they have got their act together and have taken away points.
The trial into City, owned by Sheikh Mansour, is expected to get underway on Monday
'They have an economic dumping that was damaging to Spanish football. We could not do the same because we would return to 2010, when clubs disappeared due to debts.'
The independent hearing into the City case is anticipated to last approximately two months although the verdict is not expected to be made public until spring 2025 at the earliest, according to reports.
The sternest punishment if found guilty is relegation. Points deductions and fines are also potential penalties.
City won the Premier League three times between 2009 and 2018, lifting the top division title in 2012, 2014 and 2018.
They have started the new season strongly again and sit top with three wins from three matches.
