Spain midfielder Dani Olmo has accused Argentina assistant coach Roberto Ayala of lying about a post-match incident during the World Cup final, stating that Ayala's claim of reacting to comments was false.

During the melee that ensued after Spain's 1-0 victory on July 19, Olmo was one of four Spanish players involved in altercations with Argentina's players and staff. Video appeared to show Ayala punching Olmo in the neck.

Ayala had previously attempted to downplay the incident, describing it as "more of a shove than a punch" and a reaction to "some words" from Olmo and teammate Eric Garcia. He also issued a public apology and expressed a willingness to apologize in person.

However, Olmo refuted this account in an interview with Spanish newspaper Diari de Terrassa, stating, "Someone who says they're sorry, but justifies a punch by saying it was a response to a comment, is surely not sorry. He is lying because I didn't say anything to him, so he doesn't need to apologise."

Olmo emphasized the importance of behavior and setting an example for younger generations, stating, "What truly defines us is not the mistake, but the courage to acknowledge it with humility, honesty and dignity."

Ayala's earlier comments indicated he believed he had a right to apologize, saying, "Of course I'm sorry. Given my position, I cannot allow a feeling, or whatever I might receive from the other party, to affect my mood or my actions. For me, we need to draw a line and leave it at that."

FIFA has launched an investigation into the post-match incidents that marred the World Cup final at MetLife Stadium in New York. The investigation will assess potential breaches of the FIFA Disciplinary Code.

Argentina midfielder Leandro Paredes could face disciplinary action for his involvement in the scuffles, which included striking Garcia and tackling Spain's Gavi. Nahuel Molina also faces scrutiny for an incident involving Spain captain Rodri.

The FIFA disciplinary committee has appointed an ethics prosecutor to examine the events, with further details to be released upon completion of the prosecutor's report. Argentina could face significant fines for failing to control their players and staff.
