Ralf Mutschke, FIFA’s security chief, warns of match-fixing threat to 2014 World Cup.

FIFA’s security chief Ralf Mutschke has warned that criminals may try to fix World Cup matches this summer.

Mutschke, though, says world football’s governing body will do all it can to make sure the tournament remains clean.

Speaking to Frankfurter Allgemeine Zeitung the former Interpol man said that he would not be surprised if criminal gangs tried to manipulate games in Brazil.

“We must clearly assume that organised crime will try and fix matches at the World Cup,” Mutschke said. “At this event, bets will be placed at a great rate and a large profit will be made.”

With match-fixing a growing global threat, FIFA aims to be on its vigilant in Brazil.

“We will have security officers in all 12 World Cup stadiums,” said Mutschke.

“We will monitor all matches on the betting market, we will be in contact with all bookmakers, screen the social networks and will go through specialised forums with a fine tooth comb. We will also analyse individual incidents during games.”
