Ashes 2013-14: Captains Cook and Clarke ready for 100th Tests
Alastair Cook admits his 100th Test match will be his "toughest", while Michael Clarke is hoping to mark the same milestone by winning back the Ashes urn for Australia.
Cook and Clarke are set to reach the landmark together and each captain was full of praise for the other ahead of tomorrow's crucial third Ashes Test in Perth.
Defeat at the Waca will see England hand the urn over to Australia. The only side in Ashes history to come back from 2-0 down to win was the Australian side led by Don Bradman in 1936-37.
