DANNY Foster says Brentford are out to spring a surprise on high-flying Leeds United tomorrow.
The Bees travel to Elland Road 29 points and 12 places behind Simon Grayson's promotion-chasing side.
But Foz is out to upset the odds against the fallen giants.
He said: "I'm used to being an underdog with Dagenham . Everyone used to underestimate us but we hit them with the surprise element.
"Hopefully we can do the same at Leeds."
