"Jones still has a lot of thinking to do. First, he must work out whether it makes sense to continue with Hartley as captain," Dallaglio wrote.
"England have done well under the hooker's leadership: 24 wins from 26 test matches is a formidable record. Ideally, the captain should be one of the team's strongest players but Hartley is not. He is often one of the first players to be substituted and, again, that is far from ideal.''
He said that if the captain was not the best player in his position it wasn't a great starting point. ''I don't see Hartley as better than Jamie George. I can see why the coach might not want to change his captain but in my view there is greater risk in not making the change.
"Since the World Cup started in 1987, every winning captain has been an exceptional leader and outstanding player; David Kirk, Nick Farr-Jones, Francois Pienaar, John Eales, Martin Johnson, John Smit and Richie McCaw. I'm not saying Hartley can't lead England to victory in Japan but to do so, he will have to break the mould."
