Hiddink fears former Australian charge Cahill's impact will ruin his Chelsea farewell

COBHAM, England: Chelsea manager Guus Hiddink fears Australia star Tim Cahill could wreck his FA Cup final farewell at Wembley.

Hiddink takes charge of Chelsea for the last time against Everton on Saturday knowing a familiar face has the ability to send him back to Russia on a low-note. The Dutchman, who resumes his role as Russia coach on a full-time basis after the Cup Final, worked with Everton midfielder Cahill during his spell as Australia coach.

Cahill thrived under Hiddink's management and the duo helped the Socceroos reach the last 16 of the 2006 World Cup.
