To be fair, if evidence supports the charges and it becomes obvious that the owners are guilty, it's only reasonable to expect the club to be expelled from the PL.
Furthermore, we would almost certainly be refused entry into the Football League if the current owners retained control of the club.
It's no surprise that 'a number' of PL clubs would want City kicked out of the league if guilty. I would expect all 18 to want that to happen.
To be quite honest, if we are actually found to have cheated to the alleged extent (or admit to having done so), I would expect most decent City fans would want the owners to leave the club and be kicked out of football.
For the good name of Manchester City Football Club, we can only hope that the owners of the City Group are the decent, honourable, and honest people that Pep Guardiola believes them to be.
