DUBLIN, May 20: Bangladesh take on the West Indies in the World Cup here on Friday after being told by their coach that it is time for them to play cricket as well as they talk it.Gordon Greenidge, the former West Indian star, said he could provide the players with stacks of inside information on their Group B opponents. But once the toss had been made, it was up to them to make use of it.Greenidge said: ``The boys are forever talking about doing it but when they get the opportunity, they seem to forget what they've been talking about. We have tried to install some positive thinking and cricket knowledge into the guys and also to apply ourselves in terms of the game, but it just doesn't seem to be working. For some reason, we seem to stop playing cricket and do a lot of crazy things out in the middle.''Greenidge, however, sees little hope of Bangladesh pulling off an upset if they play like they did against New Zealand on Monday when they were bowled out for 116 to lose by six wickets.The WestIndies skipper Brian Lara, meanwhile, had problems of his own as middle-order batsman and left-arm spinner Keith Arthurton was ruled out of Friday's match due to a sprained ankle. His absence means the team, who lost to Pakistan by 27 runs in their first match, will have to include an extra bowler at the expense of an all-rounder.Lara, the cornerstone of the West Indian batting, is himself under pressure to perform, making just 11 against Pakistan before getting out to a loose shot.
