Afghanistan captain Gulbadin Naib is confident his unheralded side will not suffer from stage-fright when they play holders Australia in their World Cup opener. Naib s team go into the tournament as 100-1 outsiders and few expect them to shock Australia in Bristol on Saturday. When they met Australia at the 2015 World Cup in Perth, a 275-run defeat ensued as David Warner hit 178 in a total of 417 for six.
