Windies have some really dangerous players and Waugh believes they will provide a stern test to five-time champions when the two face off at the Trent bridge on Thursday.
"The West Indies will provide a more realistic gauge on how the team are tracking, for they possess a squad full of matchwinners that can dominate if they gain any sense of ascendency in a match," Waugh wrote in a column on the International Cricket Council's media page.
"They are the most watchable team in the tournament with a batting line-up that can kidnap any bowling attack with brute force.
"No ground is big enough when this behemoth of a batting order clicks into overdrive but they also have vulnerability against high-quality bowling as they tend to play one dimensional at times."
Not only with the batting, Waugh was impressed with the bowling prowess of a team that that polished off Pakistan for a paltry 105.
"Every side in this tournament will be wary of playing the Windies and I wouldn't want to face them in a knockout match.
