OK, perhaps starting from now we should insert something like this to every player contract that will be signed in the future:
"If desired by the club, the player has to renew or agrees to be sold by the club to any club deemed appropriate by both the club and the player, no later than 6 months before the current contract expires. If the player refuses to do so, he/she will not play and be sent to the stands for the remainder of his/her contract. ".
Let's see if this will work.
Unfortunately, the difference between seeking agreement IN EARNEST, then seeking a solution (sell, stay) in case of no agreement again IN EARNEST
AND having a malicious strategy at work behind the club's back
cannot be formulated in a FORMAL LEGAL language
The best that the club can do short-term is include clauses that are unilaterally triggered to extend players contracts for 1 year, with reduced wages.
And trigger them when the Moussas of this world pull off similar shows
Long-term sustainable solution is UEFA and FIFA to intervene and stipulate certain conditions for a player to get sold before the end of contract.
Like they are intervening now to limit the power of super agents
