They management should because Yamal really got to get compensation for all he did for his club this season and the only way is by implementing what you just said, i somuch love the movement of that guy, I think he is second Lionel Messi in the making, what I will have to say is that Barcelona as a team should work like this as the did this season for the next season, atleast they have learnt a lot with what they achieved this season as a result of team work, at the beginning of the competition for the just to be conclude season in the laliga, I never thought that Barcelona will bag the two trophies with all they were going through then but here we are celebrating a well deserved success by the team, they achieved all this because they know there status then and never allowed it to affect their performance unlike other teams that got all it takes to get the same result as Barcelona but failed to do so because of mispriority.
