Ashes 2013: Michael Clarke says Australia can still win series

Australia captain Michael Clarke believes his team can still win back the Ashes despite being 2-0 down in the five-match series.

Ahead of Thursday's third Test at Old Trafford, Clarke could not say whether batsman David Warner would return to bolster a struggling batting line-up.

If Warner plays, it will be his first appearance for Australia since he was suspended for punching England batsman Joe Root in a bar.
