Talking about unpredictability, I do think that Australia should win the finals but as we all predicted earlier that Pakistan will surely play in the finals we can be wrong this time too. Pakistan did lock for better than Australia but some mistakes cost them that match. Let's see what happens in the finals but I do think Australia will win if not something miracle happens.
In the semi finals, both teams chasing won the match and that was a common format we saw throughout this tournament. So i would say that the toss will be an important aspect as the team winning the toss will bowl first and i am going to bet on the team chasing. I am waiting for the toss and i might be placing a couple of hundred dollars and see how it will go.
