Cape Blanco will attempt to display that his Dante Stakes victory over Workforce was no accident when both Derby winners challenge again in a scintillating King George VI And Queen Elizabeth Stakes at Ascot on Saturday.
Vindications were attempted for Workforce after he was defeated by the Aidan O'Brien charge in the huge Derby trial at York in May, with the bit passing through his mouth.
But it hadn't been smooth sailing for Cape Blanco, as well as he came up sore after the event.
Workforce, trained by Sir Michael Stoute, made reparation in dramatic form in the Investec Derby while Cape Blanco failed in the Prix du Jockey Club only to run to victory the Dubai Duty Free Irish Derby on his last start.
O'Brien is anticipating the rematch in the midsummer major event, sponsored by Betfair.
"We've been very happy with him since the Curragh. We always thought very highly of him and the only blip on his copybook was France. We just put that down to an off-day," the Ballydoyle handler told At The Races.
"The Curragh was the first time he'd run over a mile and a half and he showed all the courage and class we thought he had in the Irish Derby.
"He did finish sore after the Dante. He cut the back of his heel.
"We were very happy with him going to York. It was his first run of the season and most of our horses have been coming on for their first run. A few days after York he was perfect.
"He came out of France very well and we were happy going to the Curragh with him. It's going to be exciting."
Colm O'Donoghue saddles up for the plum ride, with stable jockey Johnny Murtagh under a suspension.
"It's great to get a ride like Cape Blanco in the King George and I'm really looking forward to it," he said.
"Cape Blanco is very uncomplicated. I can ride him anywhere I want. I'll just have to ride the race as it unfolds in front of me.
"He showed how good he was in the Irish Derby. It was a very good performance."
