This is the best decision for both parties. Because that way Pogba can also establish communication with other clubs who might also be interested in the player's services. And I'm happy because in the end Pogba didn't receive any heavy sanctions. He managed to get relief because it seems he did not intentionally use doping. This will also improve Pogba's reputation.
With Pogba, reputation was damaged but now it is no longer too important with him. Having second chance to continue his career and working for salary are more important with him now. The contract termination immediately is good for both Juventus and Pogba and they can end this work contract and relationship with happiness or at least no conflict of interest.
Regarding Marseille's interest in Pogba I hope it becomes a reality. because if Pogba joins the French club Marseille, it will be a good reunion between Pogba and Mason Greenwood, who once played together at Man United. And currently Marseille is also coached by a fairly qualified coach, namely Roberto De Zerbi.
Pogba perhaps does not mind about chance to reunite with Mason Greenwood. He has bigger priority like playing well and in a league that can help him to be called for France national team, or another priority like salary and if his main concern is salary, he will aim at Saudi Professional League.
