The Argentine national team lost a very important player before the World Cup.

Most reliable journalists report that Giovani Lo Celso will undergo surgery due to a groin muscle injury and will miss the World Cup.

The defender, who has been suffering from the injury since last weekend, has been a question mark regarding his participation in the upcoming tournament.

As the media reports, G. Lo Celso did everything he could to represent the Argentine national team at the World Cup. He was even willing to sacrifice his two-month salary, as "Villarreal" (the loan club) and "Tottenham" (the club he belongs to) insisted that he undergo surgery.

The Argentine was a starting player for the team and also significantly contributed to the national team's triumph in the "Copa America" championship.
