FIFA has appointed American referee Ismail Elfath to officiate the highly anticipated World Cup semi-final match between England and Argentina, a decision that has intensified scrutiny surrounding the tournament.

Elfath, who will be assisted by compatriots Corey Parker and Kyle Atkins, will take charge of his fourth World Cup game on Wednesday at Atlanta Stadium. This marks the most significant assignment of his career.

Argentina's progression to the semi-finals has been met with controversy, particularly following their matches against Egypt and Switzerland in the knockout stages. Egypt had a goal disallowed, and Switzerland's Breel Embolo was sent off, leading to accusations that FIFA is favoring Argentina and Lionel Messi in an effort to secure him another World Cup title. FIFA has consistently denied these allegations.

Elfath's history with Messi includes officiating four club-level matches since Messi joined Inter Miami in July 2023. In all four of those matches, Messi's team emerged victorious. Elfath also served as the fourth official during the 2022 World Cup final when Argentina defeated France.

In the MLS this season, Elfath has shown a tendency to issue cards, having issued 41 yellow cards, three red cards, and awarded three penalties in 10 matches prior to the World Cup break. Across his three World Cup matches this tournament, he has shown eight yellow cards and one red card.

Concerns over officiating have been voiced by other teams as well. Following Spain's narrow defeat to Uruguay, Spanish media criticized Elfath's performance for not being firm enough with the Uruguayan side. Switzerland's defender Manuel Akanji claimed that "everything was against us" after their quarter-final exit, and manager Murat Yakin called the refereeing "incomprehensible." The Swiss team was particularly incensed by a red card shown to Breel Embolo following a VAR review, which they believed was a mistaken identity call.

FIFA's Chief Refereeing Officer, Pierluigi Collina, has defended the officials against accusations of bias. Collina stated that "unfounded allegations have no place in our sport" and that "nobody can question the integrity of the FIFA World Cup match officials." He emphasized that referees make honest decisions independently and are not influenced by anyone, including FIFA President Gianni Infantino.

Despite these assurances, the scrutiny continues as Argentina aims to reach back-to-back World Cup finals. The semi-final clash with England is set to be a high-stakes encounter, with Elfath at the center of the officiating duties.
