It wont be a walk in the park but in all honesty ( Not having Australia, England and New Zealand) is a huge plus for Pakistan, In Aussie Conditions all three teams can be dangerous. Afghanistan maybe wont be that strong in Australian Conditions, but they can be a tough team for Pakistan as we saw in the Past.
India and South Africa will be Pakistan Hardest Match, but im sure they will win 1 of those matches, ideally if they can win both that is perfect.
Bangladesh and even the other teams that qualify can still be tricky but I would back Pakistan to win those matches.
I do think like always Team selections, and team combonation for the correct opponent will be important in these conditions.
For some reason I feel maybe Pak will have a slow start, but will make the right changes, and will squeeze their way into the semis, and peak at the right time. Its hard to say if they will win the whole thing, but I think Semi Finals should be possible if they select the right team for Australian Conditions.
