Also I believe the Argentina dressing room, Messi et al, effectively took over the running of the team from the manager, Jorge Sampaoli, during the quali period when Messi returned. Apparently that is why the likes of Icardi was not even considered for their 23 man squad - not the manager's call but that of the dressing room with players who were not gonna play for Sampaoli unless they 'played it their way' and he stopped trying to change their style of footie. I notice Mascherano immediately retired after this match and I'd bet a wad of money that he was part of the 'gang'! There will be others who will follow him and deservedly so!
