I do not think that FdY will want to leave for salary reason. Who might be interested to take him except a team who has a Nederland coach? The only one I am thinking might be Liverpool, but not sure if they may want him. Other teams may pay him much worse than Barca hence, he will stay and it would not come to my surprize if Barca will not extend his contract. Nothing new.Haha no Gavi and Casado both pass the ball back and safely more than FDJ and neither will be the DM at Barca if FDJ leaves. They will go for another midfielder.
FDJ is one of most progressive passers in the team is the reality and much more so than likes of Casado and Gavi. He also creates more chances. involved in more moves that lead to goals etc, more through balls to cut lines.
But dont let truth get in the way.
