Fifa confident over 2014 World Cup security after Copa Sudamericana Final

Brazilian team Sao Paulo were crowned champions after Tigre refuzed to return at pitch after break,claiming their players had been attacked by security staff in the dressing rooms during the interval.

Fifa comment :  "FIFA cannot comment on the incidents at the match in question, as FIFA were not involved in this match operation.However, for the FIFA Confederations Cup and the FIFA World Cup there will be a comprehensive security concept for the stadiums in place developed by the local organising committee together with the respective authorities and reviewed by the FIFA security experts.

"The FIFA Confederations Cup will be the first football competition in Brazil to use mainly private stewards for safety and spectator services as it is already a standard procedure in many countries around the world.

"This is already a legacy as through this initiative more than 30,000 security officers will be trained and certified to work during the FIFA Confederations Cup and FIFA World Cup in Brazil. FIFA has full confidence in the security arrangements developed."

CONMEBOL official Romer Osuna said: "The referee abandoned the game because it was not right to play on. This decision is final. It is a shame that a continental final finished in this fashion."
