The pair are locked in a battle for the jockeys’ title, with Moreira three ahead of Purton, and the duo will be teaming up with Savvy Nine and Eagle Way respectively.
Eagle Way makes a quick return to action after finishing third in last week’s QEII Cup.
Moore said: “Eagle Way is the best stayer in the race, just look at his third last Sunday.
“But, when you take into account the 2400 metres with top-weight of 133lb on his back, it’s going to be tough. I’m not worried about backing up quickly, he pulled up fine, I’ve had him a long time and I know he can back up in a weak race.”
Moreira will be riding Savvy Nine for the first time, with the four-year-old having finished fourth on his penultimate start in the Hong Kong Derby.
Moore told www.hkjc.com: “The light weight is going to be key to him, especially over that distance of ground.
“He’s a horse on the rise and he travelled very well the other day with a closing third in a 1200-metre dirt trial. The jockey got off and said he was very happy.
“He’s well-weighted but he has to be given a very good ride.”
Moore also saddles Helene Charisma and Chefano, but Helene Leadingstar is the horse in form as he seeks a hat-trick of wins for trainer Tony Cruz.
He said: “He’s got a big chance. He’s won two races already and I’m very happy with him leading into this.
“I was really pleased with his barrier trial and I expect him to show us his ability over the mile and a half, he’ll see out the distance easily.”
Moreira has a ride in all 11 races on the card, while Purton has 10 mounts.
