However, with the start of the new season, Vidmar was unable to retain the form from the previous season with a slow start by taking only 5 of the 15 available points. He has been criticised for his use of playing a lone striker. Adelaide finished last in the 2009–10 season. As a result of comments he made at a media conference in November 2009 about "beheading his players like they would do in Saudi Arabia" if they did not perform well, Adelaide United handed Vidmar a two-match touchline ban. The club also issued Vidmar a $10,000 fine. After leaving Adelaide United, Vidmar became the coach of the Young Socceroos. Vidmar was the caretaker coach of the Socceroos team for one match in 2013, after Holger Osieck's contract was terminated.
