WITH a squad top-heavy with quality such as Frank Lampard, Didier Drogba, Michael Essien and Nicolas Anelka, Chelsea will not be short of potential matchwinners at Wembley tomorrow.

But Tim Cahill believes the biggest threat to Everton’s FA Cup dreams can be found not on the pitch, but in the dugout.

Guus Hiddink will call time on his brief stint as Chelsea manager at the weekend having revitalised the flagging fortunes of the Stamford Bridge outfit since replacing Luiz Felipe Scolari in February.

And for Cahill, the impact of the vastly-experienced Dutchman is no surprise.

Hiddink was coach of the Australian national team for less than a year but that was enough to guide the country to the World Cup finals in 2006 and give Cahill the chance to make his mark on the tournament on Germany.

The Everton midfielder famously netted two goals to earn the Socceroos their first-ever World Cup finals victory against Japan, a feat which later in the year helped him become shortlisted for the prestigious Ballon D’Or award.

Hiddink had already taken an unfancied South Korea to the semi-finals in 2002 having guided Holland to the same stage in the 1998 finals, and subsequently helped Russia dump England out of Euro 2008 before reaching the last four.

At club level, the Dutchman also presided over PSV Eindhoven’s European Cup triumph in 1988.

And Cahill is left in no doubt as to the Chelsea manager’s talents.

“Guus was amazing at Australia,” he says. “He was a very regimented guy, very disciplined and set his ways very quick. No player was bigger than anyone else.

“If you see what he’s done to Chelsea, it’s obvious he’s gone in there and cleaned it up. It was messy when he got there, but it’s nice and tidy now.
