Betegy.com is probably the closest thing that you are going to get to a young Marty McFly buying 'Gray's Sports Almanac' the sports book that details all the sporting results during that time, he then travels back to the past and is armed with the correct results allowing him make the correct bets and become as rich as he chooses.
Ok, so this is far from nailed on but a 73% accuracy across all five leagues is nothing to be sniffed at.
The kind people at Betegy allowed me to trial their services and I came across their predicted Manchester United 2 Arsenal 1. Yeah right, we are going to stuff the Mancs so I decided against it.
You don't need me to tell you how that ended up. I think I will learn from my lesson though and give it another go and perhaps avoid betting on Arsenal games, instead choosing any of the teams from the Spanish, German, Italian or French leagues. Plenty to choose from.
If you are the betting type then I recommend checking these guys out. Obviously they cannot predict the future but they have their little formulas so please bet responsibly.
