Australia captain Aaron Finch says disgraced stars Steve Smith and David Warner will use the World Cup to restore their world-class credentials after their role in the infamous ball-tampering scandal in South Africa.

Smith and Warner served 12-month bans following the sandpaper-gate incident in the Cape Town Test in March last year and Smith lost the Australia captaincy as a result.

Both players are back in the Australia squad for the World Cup in England and Wales and are set to start their country s first match of the tournament against Afghanistan in Bristol on Saturday.
