Norwegian FA president Lise Klaveness added: "The annual congress is the single most important body to ensure good governance of international football.

"The situation is concerning. Member associations have travelled from all over the world to participate at this congress here in Paraguay, expecting professional leadership and dialogue at the highest level."
