England have not won a Test in Australia since their successful 2010-11 tour

England will beat Australia "quite comfortably" in the Ashes if captain Ben Stokes is fit enough to play all five Tests, says former batter Mark Ramprakash.

The series begins on Friday in Perth with England looking to win the urn down under for the first time since 2010-11.

Stokes has recovered from a shoulder issue to play but has missed matches in each of England's past three series because of injuries.

Ramprakash, who also worked with Stokes during his time as England batting coach, pointed to the all-rounder's ability to balance the side but also his leadership.
