Wow, those are some really tempting multipliers! If I had to choose one out of those considering the risk/reward ratio, I'd go for New Zealand.
I consider New Zealand as a good team but do they have the team to win the world cup, highly unlikely considering their history, England and Australia have the chance to win the world cup and Australia always are a competitive team in the history of world cup, they were not performing well on the built up of the tournament but i think they will perform well in the tournament and can lift the world cup once again.
Any tipsters here for cricket.
