The fall-out from the World Cup opening game's high-profile refereeing blunder continued on Friday with Croatia's players questioning the appointment of Japanese referee Yuichi Nishimura for the match against Brazil.
Nishimura awarded a penalty against Dejan Lovren despite the Southampton defender barely touching Brazil striker Fred - the scores were 1-1 at the time and Brazil went on to win 3-1.
Such a controversy was the last thing that World Cup organisers wanted - and will fuel calls for FIFA president Sepp Blatter's proposal for challenges via TV replays to be approved.
Nishimura is an experienced referee who was fourth official for the 2010 final, but Croatia's former Tottenham defender Vedran Corluka questioned why he was appointed for this game, claiming no one could understand him - though it is a requirement for World Cup referees to speak English.
Corluka said: "I never saw in my life that a referee don't speak English. He was speaking something in Japanese but no one could understand him.
"The decision to award the penalty was embarrassing and it changed the game."
Croatia coach Niko Kovac said Nishimura had been "out of his depth" and Lovren added that if the hosts Brazil were to be favoured in such a way the organisers could just award the trophy to them now.
He said: "Of course I am angry. I wanted to cry but what can you do? If it is like this, then you can give the World Cup directly to Brazil."
Football Association general secretary Alex Horne, a board member of the International FA Board which rules on law changes, had said hours before the Brazil v Croatia match in Sao Paulo that a high-profile blunder could provide impetus for Blatter's proposal for managers to be allowed two challenges a match.
Horne told Press Association Sport: "Don't underestimate the power of circumstance. If we get something happening in the next three or four weeks that is blindingly obvious - like Frank Lampard's 'goal that wasn't a goal' in Bloemfontein - then that could give this real momentum."
Croatia face Cameroon in Manaus on Wednesday in their next Group A match.
