David Warner has declared his international career a "closed chapter" but at the same time, the Australian batting great won`t mind padding up in the Champions Trophy next year should he be selected, something that has been described as an "emergency option" by his ODI captain Pat Cummins.

Warner retired from ODIs after Australia`s World Cup-winning run in November last year, while his last Test was against Pakistan in January. His final T20I came against India on June 24 at the shortest format`s recently-concluded global showpiece.
