"He is just loving it here and I think the hard racing he has had has improved him and he has gone to another level, a level the others aren't at.
"He feels fantastic and he is used to sitting parked to win over here now, which he will probably have to do again. But I think all the hard racing he has had has toughened him up and made him even better."
Just as important as that toughness is Lazarus's soundness, which Purdon says shouldn't be a probem in the five group one races he contests over the next six weeks, ending in the Miracle Mile.
"He is very sound so all going well that won't be an issue and a lot of these top horses are facing similar programmes.
"So the six weeks might be harder on them than it is on him."
Ultimate Machete has been outstanding in Perth but with his lack of gate speed he faces being three wide for at least part of the race and that suggests a local like Chicago Bull could get closest to Lazarus, as he did in the Inter Final.
Closer to home at Cambridge tonight, trainer Steve Telfer finds himself in the rarest of all racing situations, going into a tote race knowing he will win.
Telfer trains all six starters in race two at Cambridge tonight, a feat occasionally matched in smaller non-tote races in New Zealand but almost unheard of in a proper race, especially one with some high class pacers.
"We have a lot of horses in this grade and I am grateful to the club for holding the race but it is a weird feeling knowing you are going to win it no matter what."
That has sent Telfer searching for five sets of his colours, with Valor Lustre racing in owner Ivan Court's colours. Perhaps the best of the Steve Six is American Brave, who has won three of just seven starts but comes with a warning tonight as he hasn't raced since the Sires' Stakes Final at Addington two months ago.
"He trialled well last week and was going to have another this weekend but they aren't on so he is here instead.
"Because of that lack of hard fitness I don't want him having a hard run early so he might look for cover and that can often be a tricky way to win at Cambridge," says Telfer.
"While small fields can be hard to work out I'd say our best two chances are Triple Eight and Step Up."
Telfer also has a huge chance with Ideal Roman in tomorrow's Parawai Cup as the northern grass track circuit returns.
