A young Afghan side with an average age of just 25 have vowed to give audiences back home rare cause for jubilation at the T20 World Cup (WC) after a breakthrough performance at the 50-over showpiece. Kabul’s skies were raked with fireworks when Afghanistan celebrated their stunning eight-wicket victory against Pakistan in the ODI World Cup in October. They finished sixth, ahead of defending champions England — who they also beat — stoking hopes for the T20 tournament in the United States and West Indies starting on Saturday.
