We are rumored to offer him free exit while saving his salary, and even threatening to unilaterally terminate it if he refuses
Alemany: "We have informed Dembele that he must leave immediately"
Alemany added that "today, January 20, eleven days before closing the last term of his contract, it is evident that it seems obvious to us that the player does not want to continue at Barcelona and is not committed to Bar?a's future project. This scenario has been communicated to him and his agents that he must leave immediately, because we want committed players and we hope that a transfer will take place before January 31"
Finally, Alemany said that "the sporting consequence of all this, valued by the technicians and our coach, is that we do not want to have uncommitted players with us who do not want to be at Bar?a, and therefore the fact that they do not go summoned is nothing more than a consequence of this whole process.
The club is not the one that must determine,
the coach has determined it and has our support and support. It seems to us an absolutely coherent attitude"
That's translated from Mundo Deportivo. A mutual termination of his contract requires some amount of money to be paid to the player which is second option IMO.
