Australia coach Justin Langer on Sunday hailed explosive opener David Warner’s work ethic and hunger for runs, saying he was never in doubt about his ability to come good in the ongoing T20 World Cup despite struggling for form ahead of the tournament.

Warner, 35, had been short of game time and runs over the past 12 months but made a welcome return to form on Saturday, smashing an unbeaten 89—the highest score by an Australian at a T20 World Cup—in the eight-wicket victory against the West Indies.
