Obviously no games were ever played. It would be like trying to prove infidelity because someone was making plans to cheat. The intent was there, but the act never commenced. 🤔
At a minimum you would get a strong bollocking from the missus; at worst told to sling your hook. A punishment all the same.
That the 12 clubs intended to create a breakaway league and did in fact attempt to bring it about is surely beyond sensible doubt.
FA Rule E9:
“An attempt by a Participant or any agreement with any other person (whether or not a Participant) to act in breach of any provision contained in these Rules shall be treated for the purposes of these Rules as if a breach of the relevant provisions had been committed.”
FIFA Disciplinary Code Article 8:
“ 8 Acts amounting to attempt
Acts amounting to attempt are also punishable.
In the case of acts amounting to attempt, the body may reduce the sanction envisaged for the actual infringement accordingly. It will determine the extent of the mitigation as it sees fit; it shall not go below the general lower limit of the fine (cf. art. 15 par. 2).”
