The first of those races will be the Chariots of Fire for 4-year-olds in Sydney in February, with Melbourne getting a taste of Self Assured's talents first in another 4-year-old race, the Bonanza at Melton, as he heads there to qualify for the Sydney group one.
"He won't go to the Hunter Cup though," said Purdon.
Safely through the Bonanza and into the Chariots of Fire he will then be aimed at his next major open class target the A$1 million Miracle Mile also at Menangle.
The pacing world looks his oyster, with speed and his growing manners.
Earlier in the night the All Stars' seemingly unstoppable domination continued with Winterfell, One Change and Amazing Dream taking the other features.
Winterfell's professional victory in the $100,000 National Trot could hardly be deemed a total shock coming just 17 days after he won the Inter Dominion Trotting Final, but tonight's win was a step up.
He had to be more controlled in trailing Majestic Man and then not only outsprint him but his hot favourite stablemate Oscar Bonavena.
The latter was forced to sit parked for the last lap and found that too tough against the absolute best and was beaten into third, with Majestic Man fighting back for the bravest of seconds.
But Winterfell proved once again that at Alexandra Park he is a vastly superior horse to the one who can gallop so often left-handed.
Six weeks ago he was the punter's enemy, now he has won four of his five starts since coming north and his win tonight has to take him a long way towards the Trotter of the Year title. Just as professional tonight — but using the passing lane to win from the trail — was One Change, who justified his favouritism in the $200,000 PGG Wrightson Sales Series Pace for 3-year-olds.
The former sales reject, who was passed in for $30,000, has now won both Sales Series Paces, the Sires Stakes at 2 and 3 and a Harness Jewels for almost $500,000 in stakes with so much of his career lying ahead.
He sprinted past a very brave Bad To The Bone, who was excellent in second in a race marred by the second favourite Smooth Deal being checked early and losing 40m in a gallop. His recovery to finish fifth was massive.
And Amazing Dream overcame one on the second line courtesy of a beautiful Natalie Rasmussen drive to complete the clean sweep, overpowering Stylish Memphis in the Alabar Fillies' Championship.
