He wanted them to stop celebrating loud cause some of French players are bidding their farewell to NT and played their last game, at least from what I red
It was obviously an intense match and we know the French can be cocky, antagonistic and emotional. Was clear in the 5th when the referee told captains to simmer down. But the fact that Giani went in the middle of the Argentinians and told them they were celebrating too loud in a match that was decisive for 1/16 round for the winning team is absurd, immature and unsportsmanlike.
