So in other words, Doucoure and DCL not being signed to collect additional wages is nonsense.
They arent signed because no one wants to pay what they want. Rule 19.2 clearly says that after their contract expires on July 1st, A. The club pays them one additional month of their normal wage. B. If they sign with anyone within that month, for LESS than the club is paying them, the club makes up the difference.
So whether they sign, or dont sign, they get paid the exact same money. They gain absolutely nothing by waiting a month to sign with a new club.
