Aidan O'Brien had made a strong hint earlier this week that the colt will ride in the mix but decisions were still to be made about his jockey.
O'Brien's son, Joseph, has been unable to make the weight of 8stone 11lb to ride Ballydoyle's 2000 Guineas winner so Dettori, one of racing's most famous jockeys, will take over the reins.
Joseph will instead ride stablemate St Nicholas Abbey. But can Camelot perform to high expectations on Sunday in another high-profiled race after the disappointment of the St Leger?
Camelot failed to gain the triple crown at Doncaster last month that Nijinsky did so well and his participation in the Arc was left in the air since his defeat. I believe that Camelot raced well on the day but he just got beat. O'Brien knew where he went wrong and I hope he corrects his preparations by Sunday.
There is no doubt about the fact that Camelot can produce world-class performances and he is capable of winning more prestigious titles. But with so much hype constantly surrounding this horse, O'Brien has to be prepared to act brave.
Camelot has shown he can be beaten and O'Brien has to be sure that he won't disappoint again. After the Gold Cup, the Arc is arguably the next biggest race in the sport's calendar and the team need to be sure of a confident ride.
Do you fancy Camelot's chances in the Arc? Or do you think his recent St Leger defeat has shaken his racing ability?
