Do bookies take results from games played over 10 years ago into consideration then? Seems a bit strange. It doesn't really affect todays results, completely different players, managers, tactics, etc.
I'm sure it's probably a factor, albeit not a major one. I always like to look at head to head records though I admit going back 16 matches was perhaps a bit far but it is a pretty terrible home record and it seems it doesn't matter which manager/players/tactics we use we very very rarely win.
