BRISBANE  Darren Sammy wants the West Indies to play like world champions when they meet Australia in a one-off T20 on Wednesday. Sammy said his men have not played like the team that won the World T20 title in Sri Lanka last year and is therefore promising the Aussies a show at the Gabba. "We have to come and play like true champions. We are the World Champions and we want to showcase our skills and show the people of Australia what we have."
