He went for Hawk Wing, only to be beaten by High Chaparral, ridden by Johnny Murtagh, and he fears being wrong again.

“It was a close call and it is very possible I could be on the wrong one. There’s not a lot between them. Whoever gets the best run could swing it their way,” he told attheraces.

“Hopefully Brian Boru will improve. He has to improve, but all our horses have been improving from their first run.

“The handicapper says he’s probably just marginally the best of our horses. I always knew from last year that he was probably my Derby ride and I’m hoping that I am right.”

Brian Boru only finished third to Alamshar and The Great Gatsby in the Derrinstown Stud Derby Trial at Leopardstown last month on his seasonal reappearance but he was giving the first two 5lb.

“The Leopardstown race wasn’t run to suit my horse’s strengths. They went steady then they quickened in a hurry from about four out and at that point The Great Gatsby had probably got eight or nine lengths start on him and Johnny Murtagh on Alamshar had about four on him. And he was trying to give them 5lb as well,” said Kinane.

“You’d have had to be a good horse on the day to do that. So whereas my initial reaction was that I was a shade disappointed I feel that he will improve for that performance.”

He feels that Alberto Giacometti, third in the Prix Lupin to Dalakhani and Super Celebre, who were first and second in last Sunday’s Prix du Jockey-Club, also has a good chance.

“Everyone says the French form is strong,” added Kinane.

“How strong that will be, you will have to gauge through Alberto Giacometti. He was disappointing on his first start at Leopardstown but left that a good bit behind him.

“I was impressed with the French race and thought they were smart colts.

“I think a mile and a half should help this colt."
