O’Brien has never made any secret of the regard in which he holds the son of Wootton Bassett, who missed the second half of last season with a setback.

However, he suffered a short-priced defeat on his long-awaited return to action in the Gladness Stakes at the Curragh and was subsequently scratched from the Guineas along with stablemate Gstaad, albeit by mistake following a computer glitch.

O’Brien has previously suggested Albert Einstein could revert to sprinting, but he is first set to tackle seven furlongs for a second time in the hope of giving his trainer a better idea of whether he could potentially be supplemented for the the first colts’ Classic of the year at a cost of £30,000.

“At the moment he’s going (to Newbury),” O’Brien said at Leopardstown on Wednesday.

“Obviously if he goes to the English Guineas we have to supplement him and we want to be fairly sure if we are supplementing him.”
