Aidan O'Brien says he is 'delighted' to have Frankie Dettori on board Camelot in Sunday's Prix de l'Arc de Triomphe.
The ever-popular Italian, who has won the Longchamp race three times, has come in for the mount with O'Brien's son, Joseph, unable to do the weight of 8st 11lb.
O'Brien junior instead rides stablemate St Nicholas Abbey.
Reporting Camelot in "good form" since his second place in the Ladbrokes St Leger that denied him the Triple Crown, O'Brien said: "Frankie is a great rider, he has all the experience in the world, and we're delighted to have him."
Ground conditions in Paris are soft, and O'Brien added: "We're hoping for not too much rain - we're hoping for English good to soft.
"He's in good form since Doncaster and the mile and six (in the St Leger) might have extended him too far there. We've always thought he was very special."
O'Brien is also pleased with St Nicholas Abbey, who is returning to a mile and a half having run the last twice over 10 furlongs, most recently chasing home Snow Fairy and Nathaniel in the Irish Champion Stakes.
He said: "I'm very happy with him. His preparation has gone brilliantly and he loves a mile and a half."
