Pakistan and England are the two teams which are dominating this tournament. Also it look like that Pakistan and England will finish up on top of their groups and hence will not meet in the semi final stage of the tournament.
Many people are predicting Pakistan Vs England Final and if you want to know the winner of this match, you need to see the 1992 WC final between these two teams.
But one thing I would like to bring in here from history is that a team that has won all their matches in group stages/ Knockouts has never lifted that World Cup. So far all throughout the t20 world cups, this has been true. Moreover, things become quite different once you enter knockouts, If I am betting obviously an intelligent bet would be on England or Pakistan but I think it's way too early to say this.
