Brian O'Driscoll calls for Sam Warburton to captain Lions

Brian O'Driscoll has backed Wales international Sam Warburton to captain the British and Irish Lions on this summer's tour of New Zealand.

Cardiff Blues flanker Warburton, 28, who captained the Lions in Australia four years ago, is favourite to lead Warren Gatland's side again and former Ireland and Lions captain O'Driscoll believes he is in the best position to take up the duties.
