Trainer Mike Moroney welcomes back sprinter Tribal Wisdom in the Group One Galaxy and will be represented from both sides of the Tasman in the Group One Rosehill Guineas.

Victoria Derby placegetter Chapada is trained from his Flemington stable while Arrogant has travellied from New Zealand for his Australian debut in Saturday's Guineas (2000m).

Tribal Wisdom has not raced since defeating Osborne Bulls in a Benchmark 99 class race during Randwick's autumn carnival last April and lines up in the Galaxy (1100m).

Moroney does not believe there is much between the two three-year-olds in the Guineas over 2000m.

Chapada has had two runs since his Victoria Derby placing with Moroney saying his last placed finish under Damien Oliver in the Australian Guineas on March 2 should be forgotten.

"I always thought once we got to 2000 metres that's when Chapada would start getting into it," Moroney said.

"I'm not too concerned with his last start as Ollie wasn't that hard on him.

"He tried him but he had a tough run and he suffered a bit of heat stress as well.

"He's recovered well. He's a tough horse, he eats everything and a lovely horse to train."

Moroney says Arrogant holds good New Zealand form, although he has only scored on one occasion from eights starts.

"I don't think there's a lot between him and the horse of Murray Baker's (Madison County) that ran fourth up there the other day," Moroney said.

"He was a bit luckless behind him in one of the Group One mile races and then he didn't have a lot of luck in the (NZ) Derby.

"He had a tough trip and still went well after just getting beaten in the lead-up.

"He brings good form over and is also a lovely horse to deal with."

The trainer said Tribal Wisdom's long lay-off came about when he suffered a badly pulled muscle.

Tribal Wisdom is an outsider and meets some quality sprinters first-up on Saturday including Redzel, Ball Of Muscle, Nature Strip and Graff and Moroney just wants to see the gelding come through his return run unscathed.

"It's a tough test for him first-up but we're on our way to Queensland for a tilt at the Stradbroke in June," Moroney said.

"This is a nice starting point for him so we'll see how he's come back and we'll get a guide on how he's going."
