Ivan Bebek became a referee in the first league when his father was chief of the referees commission. At that time he was only 23.
Bebek was a Premier category referee which meant he had a chance to move up to become an Elite ref, but halfway 2011 he was put back in the first category.
Ivan Bebek is slowly working his way up, from qualifiers to a match in the group stage of the Champions League and the round of 16 in the UEFA Cup, both 2007.
The Croat went to EURO 2008 as a 4th official.
Until February 2010 Bebek was on the short list of referees for the 2010 World Cup in South Africa. But his name was not on the final list, not being an elite referee he would have never have been more than a stand-by or maybe 4th official.
