There are two matches today, one is between the Pakistan and Afghanistan and the 2nd one is between England and Australia, both the matches are between the top teams, as these all teams are trying to keep themselves in the top 4 to qualify for the semi finals and win the World Cup trophy. As in between Pakistan and New Zealand, New Zealand is still favorite as they have some good batting power hitter who can score more than 400 runs and they played well.
Whether in Australia and England, Australia would be considered as favorite team, they had also score 399 in their recent match and they have the ability to score more runs and beat the England, as England is completely out of the form now days and I don't think they give a tough time to Australia.
