Chelsea manager Guus Hiddink fears one of his former Socceroos stars will spoil the party in this weekend's FA Cup final. Everton's Tim Cahill is the man Hiddink is wary of with the Dutchman knowing exactly what the 29-year old is capable of.

"But of course I know Tim from my Aussie period," said Hiddink.

"It was beautiful to have him in my own squad but having him as an opponent is not nice.

"He is very determined and very decisive. Everton are very organised and he is the kind of player that can make a big impact on top of that discipline.

"He is a wonderful talent, very sharp, full of impact and dangerous around the box."
