Colombo: Having lost to Australia in their World Twenty20 opener, West Indies would not have the luxury of experimenting against Ireland here on Monday, as they need a win at any cost to book a berth in the Super Eights stage.Although West Indies start as clear favourites, especially with Chris Gayle in smashing form, the William Porterfield-led Irish side has a penchant for springing a few surprises at the big stage.West Indies would make the mistake of taking Ireland lightly, only at their own peril.The Darren Sammy-led West Indies, despite losing to Australia by 17 runs via the Duckworth-Lewis method here on Saturday night, showed that they have got the team to go the distance.Big-hitters like Chris Gayle, Marlon Samuels, Kieron Pollard can destroy any side on a given day. The glimpse of their brilliance was on display on Saturday when both Gayle and Samuels smashed half-centuries each to help West Indies post a competitive 191 for eight.While Gayle made a blistering 33-ball 54, Samuels raced his way to a 32-ball-50.The Irish won both their warm-up matches in the before going down to Australia in their first league match of the tournament.Despite their none-too-impressive performance against the Aussies, the O'Brien brothers -- Niall and Kevin -- showed what they are capable of during their 52-run fifth wicket stand, which helped Ireland reach a total in excess of 120, after reeling at 33 for four at one stage. Niall also scored a fabulous 62 that helped his side to beat Zimbabwe in a warm-up match.Besides the O'Brien brothers, the others also should not be taken for granted.
