Argentina midfielder Enzo Fernandez was sent off during the final against Spain, a dismissal that drew sharp criticism from analysts reviewing the match.
The ill feeling between the two teams spilled beyond the final whistle. Leandro Paredes was also shown a red card following a melee, while an Argentina assistant coach was captured striking a Spanish player as tensions threatened to escalate.
Fernandez was later pictured apologizing to Argentina fans as he left the pitch at MetLife Stadium in New Jersey, where Spain secured victory with a single goal.
Commentators described Fernandez's sending off as a costly error. Having already been on a yellow card, his challenge reduced Argentina to ten men and, in their view, handed Spain a decisive advantage.
One analyst argued the midfielder's decision-making had undermined his country despite his earlier contributions in the tournament. The red card for dissent and a reckless tackle were labelled needless and damaging.
Separately, Paredes faced criticism for his conduct after the defeat. Observers noted that while Argentina defended resiliently, his post-match behaviour was unacceptable regardless of the result.
Attention also turned to Spain's defensive display. The team's tactical discipline and ability to frustrate opponents were highlighted as key factors in their success.
Teenage defender Pau Cubarsi received particular praise for his composure at the age of 19. Analysts credited his football intelligence and the guidance of experienced partner Aymeric Laporte for his standout performances.
Spain's individual accolades included the Golden Ball for captain Rodri as the tournament's best player. Goalkeeper Unai Simon claimed the Golden Glove, and Cubarsi was named best young player.
France forward Kylian Mbappe made history by winning the Golden Boot for a second time, finishing as top scorer with ten goals.
