Emiliano Martinez's celebrations were "stupid" and dampened Argentina's World Cup victory, says Patrick Vieira who won the title with France in 1998.
Martinez shone in the penalty shootout win over France in the final, but was panned for some of his actions, which included a rude gesture with the Golden Glove he was awarded as best keeper.
He also repeatedly mocked France striker Kylian Mbappe.
Vieira, who now manages Crystal Palace, said: "Some of the pictures I saw from the Argentinian goalkeeper, I think, take away a little bit what Argentina achieved at the World Cup.
