my prediction :
top 4 teams :australia,england,india,pakistan
top batsmen:warner,butler,rohit ,rizwan
top bowler:hazzlewood,shaheen afridi,reece topley.
underdogs worth to bet:
West indies --these guys are beast and they won 2 titles (getting 1 is dream for many teams)
new zealand ,south africa teams looks very weak .
All predictions are good about winner of the title but here problem is all cricketing fans are known this T20i is unpredictable format because on his day any team can produce amazing performance and big teams can go down badly as we have few days back in Asian Women Cup where Pakistani Women's beat Indian Women's after six years even India is currently at the top of Asian teams and just one day before Pakistan lost match against team like Thailand.
So, how things will be work for teams in this event never been easy specially Australian conditions are not favourable for many Asian teams so for me right now giving any solid prediction is never been easy but still I have feeling you all teams and players can do much good but Shaheen Afridi is coming from Injury, so he can face some issues with all batsmen are in good form, and we can expect another hell for many bowlers as right now cricket is completely batting game and also favourable for batsmen.
