July 15 will now be celebrated annually as Argentina's National Football Day. The AFA confirmed the date will be celebrated annually after Lionel Scaloni's side overturned England 2-1 in Atlanta, where goals from Enzo Fernandez and Lautaro Martinez sent Argentina into a second successive World Cup final.

The decision was approved by the AFA Executive Committee and the Professional Football League under federation president Claudio Tapia.

The banner displayed by Argentina's players after the victory, bearing the words "Las Malvinas son Argentinas", will be presented to Argentine veterans of the 1982 Falklands War.

Why Argentina Chose July 15 as National Football Day

The AFA said the new observance celebrates not only the victory over England but also the wider achievements of Argentina's national teams.

"The tribute is not solely for that milestone achieved by the senior national team. The recognition is, of course, also for each and every one of the national teams - youth, men's and women's - that train day in and day out at the Lionel Andres Messi complex with the hope, joy, and responsibility of defending the national colours."

July 15 was chosen to mark the semi-final specifically. Argentina came from behind to beat England in Atlanta before losing the final to Spain.

The decision to establish a permanent day of recognition for the victory came as defeating the Three Lions "set the whole country alight, with people flooding the streets in pure celebration," the statement said.

Before kick-off, Argentina supporters booed "God Save the King", while the team's players displayed a banner reading "Las Malvinas son Argentinas" during their post-match celebrations. Midfielder Leandro Paredes later defended the message, saying the Malvinas would always belong to Argentina.

What Happens Next in FIFA's Investigation

FIFA opened disciplinary proceedings against Argentina over the banner shortly after the semi-final. Citing possible breaches including discriminatory chants and gestures, team misconduct, and security and protocol failures.

FIFA has yet to announce the outcome of its disciplinary proceedings. The AFA has confirmed National Football Teams Day while that case remains open.
