yes you're right England played more match before this t20 series it has helped to England team to win the series and i am also happy with Australian preformed in final t20 match because previous both t20 matches gives big lose for me and i gain 3x profits in final match.
Well match fitness will always play a big role in matches and as England has played a lot of cricket in the past few months the whole team are match fit where as Australia haven't played since the start of the year and there is a big difference between playing matches and practice matches so that is why I gave England the edge in this series but hopefully now that Australia has 3 matches under their belt that they now start to perform a lot better in the ODI series.
