UEFA president Aleksander Ceferin skipped Sunday's FIFA World Cup final in an apparent protest against FIFA, according to British media reports published Monday.
The move is the latest sign of growing tensions between European football's governing body and FIFA, the global governing body of football.
One major source of friction was FIFA's controversial decision to overturn the suspension of United States forward Folarin Balogun before the Americans' World Cup match against Belgium.
Balogun had been sent off in the previous game, but FIFA reinstated him after U.S. President Donald Trump publicly urged FIFA president Gianni Infantino to "review" the red card.
UEFA was unhappy that Infantino bowed to what it viewed as political pressure from the tournament hosts. It called FIFA's disciplinary committee decision "unprecedented, incomprehensible and unjustifiable" and said it "crossed a red line."
