Here is my system:

Lay correct score 0-0: It rarely happens especially with teams with blasting
attacks like Real Madrid, Barcelona, Juventus, Inter, Milan, Arsenal, Man Utd, Chelsea etc.

Those teams rarely finish their games 0-0 irrespective if they draw, lose or win.
So I have been looking closely for this kind of bet.

At Betfair you may
1) back 1 or more goals to happen in a game with odds always around 1.05, or
2) lay correct score 0-0 at odds always around 12.

The two above are basically the same. The problem of Option 1 is the little profit
that you get, and with option 2 it's the huge liability it incurs if the game
would really finish 0-0.

Last week I did some statistics of around 200 matches picked randomly from a
scores site, and basically I included all matches (even there where japanese
teams etc.).
The draw 0-0 only happened 16 times from those 200 games, so a very nice 92%
strike rate. I believe that if you are more selective, this may easily go
up to 95%-98%
When I evaluated the 0-0 scores, most of the 0-0 draws were lower division teams
unknown to me.

When I assumed a starting stake of £5 and following a very basic staking plan
with lay odds of 11, after 200 matches the betting bank had become £582!
What a nice profit.

The problem with this system is that the liabilty is so high if you are unlucky
enough to hit a 0-0 game even with high scoring quality teams.

Just last saturday I started this system with real money and bet on Man Utd, Arsenal,
Real Madrid, Roma, Barcelona and their games all had a lot of goals, so I won the bet.
