To avoid creating a mind numbingly boring post of screen shots of the various leagues that I trade I have posted just two. I was surprised by the frequency of SG scores in the two leagues pictured below. Intuitively, and from experience of trading them, I'd certainly not have had the 1-1 and 2-1 frequency in either as high as they actually are!
Ligue 2 in France, Serie B in Italy, Segunda in Spain, our own Championship and League 2 and the leagues in Argentina and Brazil (if you've the lifestyle and stamina to trade in the early hours!) have consistently been happy hunting grounds for me.
The Latin American leagues also seem to throw up many more situations where the underdog takes the lead than happens in Europe- ideal for the SG - and I'm in the process of looking at that in more detail to maybe throw up another trading angle involving laying an odds on favourites.
If you would like to have a look at the figures for other leagues get over to www.soccerstats.com. choose the league you are interested in and select 'Trends'. It's a mine of information and completely, utterly, free of charge.
