The Man City thing is such a can of worms because people seem to be convinced that they're guilty already and the question is just about how big the punishment is.
The reality is they haven't yet been found guilty. If they are found guilty of all of the charges and yet the punishment isn't severe, then that would seem outrageous and people would rightly be annoyed. If they are found guilty of only a small number and then get an appropriately minor punishment, people will still be annoyed and will say it's a stitch up, even though it will really just be a reflection of a thorough legal process. Obviously there is the argument that their expensive lawyers may have helped them get off with some of the charges also.
I think some people think that the PL will go easy on them, but from what I've read and heard on the subject, the PL are actually really keen to come down hard on them, and it's just a question of whether they can successfully prove them guilty on all of the charges. I think many people don't realise that the PL are the ones bringing the charges against them, and that it would be a defeat for them if Man City get off lightly.
