The Lion In Winter could be set for a quick return to France for the Prix du Moulin on September 7.
Favourite during the off season for both the 2000 Guineas and Derby, so far his season has not gone to plan.
Beaten as an odds-on favourite in the Dante, he was also well held in the Derby before being narrowly touched off in the Prix Jean Prat over seven furlongs.
He then proved disappointing again back up to a mile in the Prix Jacques le Marois when attempting to make all.
Despite that latest reversal, the son of Sea The Stars could now be set for further Group One action on the continent, with O’Brien confident a mile is his forte.
O’Brien said: “He’s good. We went in front on him and he didn’t like it.
“I’d say he’s probably a miler but he probably needs to take his time a little bit in his races.
“He could go back to France for the race over a mile, the Moulin, that could be him but we have others for it like Henri (Matisse) so it’s whether he runs with him or not, depending on what the lads want to do.”
