FIFA's chief refereeing officer, Pierluigi Collina, responded forcefully and swiftly to defend Barton. Collina described Iván Barton as a "world-class referee" and confirmed he was fully up to the standard required for a semifinal . In his statement, Collina emphasized that Barton's performance had been thoroughly reviewed and found to be at the expected level, effectively rebuking Deschamps' suggestion that the referee was not good enough for the occasion . Collina's defense was part of a broader stance he had taken earlier in the tournament, stating that "nobody can question the integrity" of World Cup match officials and that referees are not influenced by anyone, including FIFA President Gianni Infantino .
In short: Deschamps questioned Barton's competence and the penalty decision; Collina firmly defended Barton as world-class and suitable for the semifinal, while also defending the broader integrity of World Cup officiating.
