SBOBET are celebrating the fourth anniversary of their Principal Partnership with West Ham United by offering fans the chance to win a number of exciting prizes.

The world's leading online gaming company specialising in Asian Handicap Sports Betting and In-Play betting, SBOBET joined forces with the Hammers in December 2008.

Since then, SBOBET have provided valuable support to the club by way of shirt sponsorship, the SBOBET Player of the Month competition and a host of competitions, draws and giveaways to supporters.

To celebrate the partnership's fourth birthday, SBOBET are holding a Golden Coupon competition at the Barclays Premier League fixture with Liverpool on Sunday 9 December, with one lucky supporter winning £500!

Anyone over the age of 18 placing a bet at one of the SBOBET betting counters inside the Boleyn Ground will automatically be entered into a prize draw. All the slips will be collected immediately after kick-off and a winner will then be drawn at random.

At half-time, PA announcer Jeremy Nicholas will reveal the winner and the lucky fan will be invited to come pitchside and collect his or her £500 prize.

A second prize of a West Ham United shirt signed by the first-team squad and a third prize of a £100 Macron voucher will also be drawn.

You have got to be in it to win it, so get to the ground early, place your bets and you might just find yourself with an early Christmas present to the tune of £500 courtesy of SBOBET!
