West Indies coach Bennett King insists his team can make history in April by becoming the first ever host nation to the win the World Cup.
"I think what we've seen is a progression of our play in the limited-overs format," King said.
"The limited-overs format at the moment suits us better. The concentration levels are shorter. This amount of time is quite good. With that in mind, we are optimistic.
"The limited-overs format is an interesting game. Anyone on their given day, if they have a good day, can win a game of limited-overs cricket.
"If a side has a below par game, they can lose. What we've got to make sure of is that we don't have a lot of bad games," King told the official West Indies website www.Windiescricket.Com.
But the coach admits there is still work to do in convincing the West Indies, world champions in 1975 and 1979, that they can prevent mighty Australia from winning a third successive world title.
West Indies lost the Champions Trophy final against the Aussies in India last year.
"Our bad games tend to be the ones when we don't score over 150," said King.
"The better sides, their bad games are when they don't score over 250. We've got to work towards this.
"We've been winning games in the one-day format against really good opposition, which gives the players confidence. We've just got to maintain that consistency."
West Indies face Pakistan in their Group A opener in Jamaica on March 13 before further group games against Ireland and Zimbabwe.
