City did do something wrong as they signed to FFP rules and didnt stick to them.

The fairest way is to say all clubs in premier league as an example can spend £200m per year on transfers/wages and then you will really see who the good managers are.

As for CAS no idea but they seem to ALWAYS reduce the bans for drug cheats and one of the 3 panal members on the City case has links to Abu Dhabi to so nothing dodgy there.

Money is king always has been and always will be.
