Eddie Jones has urged the Rugby Football Union to pay for developing English coaches to enhance their skills by working in the southern hemisphere.
Jones has claimed New Zealand "control the world" and "every bit of rugby", partly as a result of their success at sending emerging coaches to Europe to provide them with an alternative outlook on the game.
It was a path trodden by former Wales bosses Graham Henry and Steve Hansen, who have masterminded the All Blacks' victories at the 2011 and 2015 World Cups, while Australia and South Africa have also benefited from personnel broadening their horizons.
Jones believes England would discover positives from a similar approach, but knows that only by picking up the salaries could his potential successors begin testing themselves in Super Rugby.
"English coaches need to get that other bit of the game which is there in the southern hemisphere - the unstructured rugby, the organised chaos," said Jones, who has performed tracksuit roles in Australia, South Africa and Japan.
"It would cost money, but the RFU could do it. The only way a Super Rugby side is going to take them is (for the RFU) to pay for their salary.
"To evolve to become a head coach is something the RFU have got to look after, not me.
"Steve Hansen and Graham Henry had stints in Wales where they rounded off their coaching experience.
"And it's no coincidence that New Zealand have become a better all-round team because of that.
"They take the good parts of the game up here, the expertise in the set-piece and taken it back to the southern hemisphere."
