No doubt Windies are the real giant and formidable force in the T-20 format and only this team has a ability to mock their opponent. I'm afraid to say but if they manage to click this year in October then i don't see any team is able to defeat them. Even World XI can't compete them when they are in form.
The West Indies squad for T20 World Cup will be like picking the best players from each of the IPL franchises and squeezing them to a 15-member side. Look at the names - Kieron Pollard, Nicholas Pooran, Andre Russell, Dwayne Bravo, Andre Fletcher, Chris Gayle, Evin Lewis, Sunil Narine.etc. These are some of the best players in this format. Other teams have a maximum of 3 or 4 T20 specialists and West Indies have 15 T20 specialists. That is the difference. Unless there are any issues with team bonding or cohesion, West Indies should be the favorites.
Romania has won the quadrangular T20 tournament in Sofia (Bulgaria). It was really disappointing. Out of the four teams participating, Romania had a team that was entirely consisted of foreigners. The only native player was Pavel Florin. Greece and Bulgaria had squads that were around 50% native and 50% foreigner. They finished 2nd and 3rd. Serbia had a 100% native squad and they lost all of their matches and finished last. The stupid ICC eligibility laws are killing cricket in associate nations. Very soon, all the associate nations will be importing players from India and Pakistan and fielding these 100% foreign squads for various tournaments. Associate cricket has become a joke.
