Not really.If City were to lose this one, it just moves to the issue UEFA want to punish City over, and that'll go down the CAS route anyway.
But if City were to win...it says UEFA are a kangaroo court. It's attacking the foundation for their decision making long before we even consider the decision.
This is a real "ouch". Even more of a declaration of war than we suspected.
CAS went against their sanctions in Milan AC case. It still doesn't stop them from doing their business as usual.
The only thing that will be damaging for UEFA is another Bosman ruling.
