Eddie Jones has labelled the Wallabies the most improved team in world rugby but says his England team will still be smarter tactically in Sunday's Twickenham showdown.
With his pre-match verbal offensive gathering steam, Jones delivered some rich compliments to his former team, declaring the Wallabies were much better now than when beaten 3-0 at home by England in June at the start of the international season.
"Having said all I've said, Australia are probably the most improved side in world rugby," Jones said.
"What they've done throughout the Rugby Championship and then on tour here is quite brilliant.
"Their attack's become a lot more varied, their alignment is better in attack, defensively they're making better decisions and key players have come back.
