Often on the day of big events bookies offer free bets for new customers. I am sure that there will be some of these around. Ususalyy you get saya £50 free bet for a £25 investment. the only trouble is that you don't get your stake money back. It's just a shame the Liverpool are 1/3. You could always try and find a few of your fellow supporters and offer them 2/1 the Hammers. Lay off £150 and you are better off than betting £150-£450 Liverpool .
If you play like Sunday then you could easily win. Liverpool overrated if you ask me (cue the abuse, only joking). They are still miles behind Chelsea.
