I'm not sure, but I don't think UEFA has the authority of handing out transfer bans. That's why they only ban/sanction clubs from Uefa competitions.
Edit: I was wrong. They can hand out transfer bans.
Max lost his entire team in one summer, which was a bunch of semi retired has beens/overrated mediocre bums like KPB, Nocerino to begin with. Minus Ibra and Silva ofcourse. Sarree never experienced anything like that
That's not a big issue though. Insisting on the clause is. I highly doubt there's any clause.
