The head of the Serbian Football Association has accused governing body Fifa of showing bias against his country at the World Cup in Russia.
Slavisa Kokeza says Serbia were victims of a “brutal robbery” during Friday’s loss to Switzerland, accusing Fifa of “directing” officials to work against them.
“We will send a protest to Fifa today,” Kokeza told the BBC on Saturday.
A Fifa spokesman confirmed a letter of protest had been received but that no further comment would be made.
Kokeza was unhappy a German referee had been appointed for a game involving Switzerland, claiming the move influenced some decisions, most notably the failure of the match official and video assistant referee (VAR) to award a penalty when Aleksandar Mitrovic was wrestled to the ground by two Swiss players.
“I do not think this is only about VAR, but that the whole thing was directed by the people who appoint referees,” Kokeza said.
“We all know too well that more than half of Switzerland’s population is German.
“Technical staff, players, people in Serbia, they are all disappointed and frustrated because of injustice some people at Fifa came up with.”
Asked how he wanted Fifa to respond, he replied: “It is clear to Europe and the world that Serbia was brutally robbed. I do not expect Fifa to take action in order for this brutal robbery not to happen again, because, I repeat, it was all directed.”
