KANSAS CITY — During Argentina’s 3-1 tense victory over Switzerland in the 2026 FIFA World Cup quarterfinals at Arrowhead Stadium on Saturday night, one detail stood out against the Albiceleste’s iconic white-and-and-sky-blue jerseys: black armbands wrapped around every player’s and coaches’ sleeve. If you’re wondering why Lionel Messi and his teammates wore this all black armband, it was reserved as a tribute for Antonio Rattin, the former Argentina captain and Boca Juniors legend who died at 89 years old after a suspected stroke on Saturday. At the request of the Argentine Football Association, FIFA granted permission for the team to wear the black armbands in his honor.
