Aussi-what????? Saudi can beat Australia in this tournament, Saudi and Iran are probably the only teams that can handle the Aussie's physically and both of them can beat Austalia.
In the WC Japan couldn't match Austalia physically but they did more than enough tactically and technically.
However, Saudi and Iran are their own worse enemy (more on that later.) Both teams have great players, specially Iran with their players that play in international leagues. But this is the Asian cup, so experience in europe may count for little and so might the interest from some Iranian players.
Unfortunately, those on charge of either federation (at least I know it's so in Saudi) can't run a farm with a donkey and two goats, let alone a federation. Right now, there is upheavel in Saudi Arabia regarding the federation. Basically, everyone is sick of their favoritism to some clubs and some players, and this is creating tension between players.
If both teams got the right direction and the right harmony, they can both play for the final. Sadly, I doubt it'd be so, and probably it would Australia vs Japan/South Korea. I am glad Saudi will play Bahrain late, because there will be tension and the brothers down the bridge would love to beat Saudi (maybe as much as winning the cup, or maybe times are different now!)
Anyway, I'd love for Saudi or Iran to win it (with all due respect to other teams) but my money is on Japan again.
BTW, a special shout out to the Asian federation, great timing! I bet those players in Europe would love to play in the middle of their holiday, specially in the year after the WC. What's next? Only allow 7 starting players and hold the final on Everest?
