why not take the Western Sydney Wanderers FC ML? they are the leaders standings and odds pretty high for choosing ML.
Adelaide United Includes a good team it's just that they are less good at the beginning of the season thus at risk if you choose Western Sydney ML
I also chose the minimum bet with odds @ 1.30 https://bitcointalk.org/index.php?topic=1179019.0
and Full time Western Sydney Wanderers FC 0 - 0 Adelaide United, your prediction draw no bet, so it's safe.
