Sam Warburton: Wales still have Six Nations title "hope"
Wales captain Sam Warburton says Wales "have to deliver" on Sunday against Scotland (15:00 GMT).
Warren Gatland's side lost their opening Six Nations match 21-16 to England in Cardiff last Friday.
Warburton says Wales have "hope" and can take inspiration from the 2013 title-winning campaign where they bounced back to lift the trophy having lost to Ireland in their first match.
But he said: "If we don't [win] then that's the championship over... we've definitely got to get a win this weekend."
