Hugely impressive in the Prix de Diane and the Prix Vermeille, the Motivator filly completed the Group One hat-trick with a truly stunning display against the colts.
A trip to Hong Kong later this year is still under consideration, although far from certain, and Head-Maarek is already dreaming of back-to-back Arc victories.
“She ate up everything last night and hasn’t lost any weight. She is just an amazing filly.
“She won the race very easily. It’s her turn of foot that is so unbelievable. When you look at the times, she ran the last 400 metres faster than the winner of the Prix de l’Abbaye and the Foret, which is incredible after a long-distance race like the Arc.
“She will stay in training next season and I don’t think we will run her again this year.
Arc runner-up Orfevre will make his final racecourse appearance in the Arima Kinen at Nakayama on December 22, a race he won as a three-year-old in 2011.
Katsumi Yoshida, chairman of owners Sunday Racing, ruled out a run in the Japan Cup for Orfevre.
Meanwhile, War Command heads a total of eight Aidan O’Brien possibles left in this weekend’s Darley Dewhurst Stakes at the confirmation stage.
Like War Command, unbeaten stablemate Great White Eagle also holds an entry in the Middle Park Stakes on the same Newmarket card.
Other O’Brien possibles include Craftsman, Friendship, Giovanni Boldini, Michaelmas, Oklahoma City and Wilshire Boulevard.
Godolphin have two representatives in Champagne Stakes winner Outstrip (Charlie Appleby) and Be Ready (Saeed bin Suroor), both of whom were supplemented at a cost of £30,000 each.
Sudirman, conqueror of War Command in the Phoenix Stakes, could take his chance for David Wachman.
Anjaal, Cable Bay and Stormardal complete the 14-runner line-up.
*Silvestre de Sousa enjoyed a 196-1 four-timer on Dullingham, Party Royal, Statutory and Aglaophonos at Pontefract yesterday.
Statutory was the star of the show for the Brazilian rider with an admirable staying performance in the Phil Bull Trophy Conditions Stakes.
