Essex can upset an excellent Kent team in the final of the Friends Provident Trophy, according to wicketkeeper James Foster.
The two neighbouring counties clash at Lord's on Saturday, which is live on Sky Sports 2 from 10.30am, to decide who will be the cup kings for 2008.
Having knocked out defending champions Durham in the semi-finals and just missed out on defending their Twenty20 crown, Kent start as favourites.
However, gloveman Foster is confident the underdogs can spring a surprise because of the amount of talented player they have in their squad.
"We're playing Kent again and they are an excellent team," he told Sky Sports News.
"They have great depth in their bowling and batting and are also a great fielding unit.
"We're going to have to play exceptionally well to win, but we think we have the players here able to do that."
Essex will certainly be hoping big-hitting all-rounder Graham Napier can perform on the biggest stage after being a revelation this season.
The 28-year-old began a record breaker when he smashed 152 against Sussex in Twenty20 action and also played his part in the semi-final victory over Yorkshire at Chelmsford.
Napier, who has been overlooked by the England selectors for the one-day series with South Africa, is determined to bring home the trophy for the fans.
"The measure of all seasons is how many trophies you win - we've missed out on the Twenty20 so this is the next one to tick off," he said.
"One-day cricket means a lot to Essex and their supporters, so it will be important for us to bring this one home."
Captain Mark Pettini gave Essex a late scare on the eve of the final when he suffered recurrence of a stigmatism during the LV County Championship clash with Warwickshire at Edgbaston.
