Quote: Pubclown "Am I right in thinking that if we finish 5th we play 8th at home, and if win will go to play loser in the 1st vs 4th game away in 2nd week?'"
That is not quite correct. The winner of the 5th vs 8th match will play the lowest placed loser from the 1st v 4th and 2nd v 3rd matches.
So if the teams finishing 3rd and 4th won we would play the team that finished 2nd. The only team we couldn't play is the team that finished 1st.
