Id agree with Els here, I can personally beat anyone as the home team in training matches, and thats the case for most other teams in the top 20, but as the away side its a huge difference. Ive won every home game for days now, but away wins your probably talking 1 or 2 a day at most in training matches.
Id personally like the training matches all to be played in two one hour windows, one each to suit Northern and Southern Hemisphere, with no home advantage. Only then can we know who the real best players are.
