Investec Derby hero Harzand could end up running in the l'Arc de Triomphe or Ladbrokes St Leger at Doncaster in the autumn.
Trainer Dermot Weld is considering a tilt at the historic Classic in Doncaster on September 10 after the son of Sea The Stars dazzled at Epsom with a length-and-a-half defeat of US Army Ranger.
Harzand's next assignment is likely to be at the Curragh for the Dubai Duty Free Irish Derby on June 25, but Weld, typically, is already playing the long game.
"He's a lovely, improving colt and I think the quality and courage came out" - Dermot Weld
He said: "Time will reveal all. He's a lovely colt and he could be an ideal English Leger horse or, indeed, if it was a wet autumn a lovely horse for the Arc."
The Rosewell House admitted he needed to add a Derby winner to his glittering CV.
Weld has broken down barriers across the world with landmark victories in Australia and America, but he had never won the blue riband event at Epsom.
That all changed on Saturday when Pat Smullen partnered the 13-2 chance to a famous victory, despite the colt suffering an injury scare on the way over.
"Life is an amazing thing," said the trainer. "Every day you value it you live but we had a very stressful, very exciting day.
"It all started when he pulled his shoe off at Dublin airport.
"I told Pat (Smullen, jockey) at the start if he wasn't happy to say so, it didn't matter to me if it was a maiden or a Derby.
"It was a long old day, with four hours of ice, but with the help of colleagues we saved the day.
"I think I had to put the Derby on my CV."
Weld was quick to highlight Harzand's appetite for a battle en route to claiming the richest race ever staged in Britain.
"He's a lovely, improving colt and I think the quality and courage came out," said the trainer.
"He's a very tough horse. When the challenge went down and the die was cast, that (toughness) is what won the day."
Smullen toasted his "greatest day in racing" after adding the world's premier Classic to his impressive list of achievements.
The eight-times Irish champion jockey has enjoyed numerous big-race victories, including the 2000 Guineas on Refuse To Bend in 2003 and eight Classics in his native Ireland.
Harzand could soon face a rematch with the four horses that followed him home in the Derby - with US Army Ranger, Idaho, Wings Of Desire and Humphrey Bogart all in contention for the Curragh Classic.
