FIFPro slams controversial kickoff times for Brazil 2014
FIFPro have raised concerns regarding the controversial kickoff times scheduled for the 2014 World Cup held in Brazil.
The international player's union have criticised the decision by Fifa to allow games to be played during the hottest part of the day in the more tropical areas.
General Secretary Theo van Seggelen told reporters: "It's an issue for us and a serious one, it's our duty to protect the game and protect the players.
"It would be unrealistic to say we would not play, that's going too far. But we would like to know why it seems not to be a problem."
FIFPro represents more than 60,000 professional footballers from around the globe and are asking Fifa to consider their views in organising the tournament.
Fifa have already come in for criticism from all quarters regarding the decision to hold games in the afternoon for broadcasting purposes despite the fact that temperatures are expected to reach ninety degrees fahrenheit.
