Football Federation Australia boss Ben Buckley has emphatically denied any Socceroos team disharmony or players unhappy with coach Pim Verbeek.Buckley described as "nonsense" reports that there were problems in the camp following the Socceroos' 4-0 World Cup drubbing by Germany last weekend.He denied claims several senior players were unhappy with Verbeek's tactics, and had approached him to voice their concerns."It's insulting to the professionalism of the players that there is speculation on speculation," Buckley said on Wednesday."It's disrespectful to the players. In no way is there any form of disunity."When asked whether any players had approached him and voiced concerns about Verbeek's questionable tactics in the Germany match, Buckley said: "Absolutely none whatsoever."All the speculation is just speculation on a very ill-informed rumour," he said.The outcry in Australia over the team's loss - and particularly the meek manner of it - have prompted speculation from media pundits and ex-Socceroos that there could be team harmony issues.Ex-Socceroo and media commentator Craig Foster even went as far as to call for Verbeek's sacking immediately.But Buckley stood by Verbeek, and ruled out any summary dismissal of the Dutchman during the tournament."I have the utmost confidence in the team and Pim and his staff," Buckley said."I don't comment on coach's tactics or coach's selections. But what I can say is the team is 100 per cent absolutely focused on this weekend's result."The Socceroos must win their Group D clash with Ghana in Rustenburg on Saturday to stay alive in the tournament.Source: Yahoo sports
