The African side lost to Uruguay in the World Cup quarter-final on penalties.
Rajevac said: “All I can say is this is football.
“It was a very difficult game for us because in the previous game (against USA) we also played for 120 minutes and in the end we had the historic opportunity to reach the semi-final and we had the penalty.
“We have to be proud of what we have achieved. This is sport and justice. Today Uruguay were the lucky ones.”
