I reckon we should round off to the nearest half goal just to give us an idea. I've tried it out on this week's games. Let's see how they go.

Birmingham City vs West Bromwich Albion (Birmingham by 2 goals)
Blackburn Rovers vs Everton (Everton by 1.5 goals)
Bolton Wanderers vs Manchester City (Bolton by 1 goal)
Chelsea vs Norwich City (Chelsea by 4.5 goals)
Middlesbrough vs Aston Villa (Middlesborough by 1.5 goals)
Tottenham Hotspur vs Southampton (Tottenham by 2 goals)
Manchester United vs Crystal Palace (Man. Utd by 3 goals)
Liverpool vs Newcastle United (Liverpool by 2 goals)
Portsmouth vs Arsenal (Arsenal by 1 goal)
Charlton Athletic vs Fulham (Charlton by 1.5 goals)

Hmmm, not sure about those predictions. You'd think there'd be at least 1 draw somewhere.
