England were tactically second rate against Ireland and would be cut to pieces by the All Blacks, according to leading northern rugby analyst Stuart Barnes.
The former England No. 10 said the All Blacks would run rampant against the narrow defensive channels employed by Eddie Jones' team if a November showdown took place.
And he said Jones was out-coached by Ireland's Joe Schmidt over the weekend, where England's run of 18 victories was halted in Dublin.
Worse still, Barnes said Ireland were not even at their best as they prevented the English from breaking the All Blacks' winning test run for a tier one nation.
"Ireland lack the firepower out wide to punish opponents of England's class with tries but if the much-touted game with New Zealand takes place in the autumn, England will be cut to pieces if they defend with the same pattern as we saw in Dublin," Barnes wrote in the Sunday Times.
