Croatia's football federation says its leaders were not involved in suspected touting of World Cup final tickets.
Prosecutors in Zagreb asked police to investigate the illegal re-sale of tickets for Croatia's 4-2 loss against France in Moscow in July.
FIFA says it is "gathering information regarding the matter" and calls illicit sales "a serious issue."
The federation, whose president is 1998 World Cup striker Davor Suker, has promised to cooperate with the authorities.
It says there were "no indiscretions"...
