THE two-year-old colts get their chance to shine in the Breeders' Cup Juvenile Turf at Santa Anita tonight.
Aidan O'Brien saddles Giovanni Boldini (Ryan Moore) and Wilshire Boulevard (William Buick), while Richards Hannon and Hughes are represented by Shamshon.
"Both of them like fast ground and we think both of them should get a mile," O'Brien.
"They are coming out of solid races and they both haven't had busy campaigns.
"They are both good travellers and are very similar. They are two straightforward horses."
The European team in the Juvenile Turf is completed by Charlie Appleby's Godolphin runner Outstrip, who is partnered by top American jockey Mike Smith.
Appleby feels the fast surface will suit his youngster, who was third in more testing conditions in the Dewhurst Stakes last time.
Appleby said: "In Europe he shows plenty of pace early doors, so I'm hoping he can show that here as well and we can give ourselves a chance of getting into a good position. We've got a nice draw in four and Mike Smith knows his way around here, so all those are pluses so far."
Trainer Charlie Hills is confident Chriselliam (pictured) will make her presence felt in the Breeders' Cup Juvenile Fillies Turf. The daughter of Iffraaj was a shock winner when claiming Group One glory in the Fillies' Mile at Newmarket last month, showing smart acceleration to pick up top-class filly Rizeena on the run to the line.
She is set to face 13 rivals in California, with jockey Richard Hughes keeping the winning partnership intact. Hills said: "I'm very pleased with her and the way she came over on the trip. She seems to be in top form. She lost eight kilos, but has put that back on – plus another four.
"We've always liked her from the word go, really.
"She trains pretty good at home and while she had a couple of starts where she didn't show what we thought she could do, she managed to put it all together at Newmarket.
"She beat some of the best that day and if she can keep on improving and handle the track hopefully she will be thereabouts."
Hughes is in similarly confident mood. "She's probably as good a filly as I've ever ridden," said the jockey. "On her Newmarket run, there was nothing flukey about it and she beat probably the highest-rated filly in Europe this year."
In a market dominated by European challengers, Chriselliam is joined by Philippe Sogorb's French filly Vorda, winner of the Cheveley Park Stakes at Newmarket.
Adding to the raiding party is Marco Botti's Al Thakhira, who clinched her second winin Newmarket's Rockfel Stakes.
The other European runner on the Breeders' Cup card is London Bridge, who is trained in Lambourn by Jo Hughes and lines up under Smith in the Marathon.
