[8][3] Paco Boy restored his reputation with an excellent win the Group 1 Prix de la Forêt over seven furlongs on the Arc undercard at Longchamp, where he beat Natagora by three lengths.

[10] Returning to Britain, Paco Boy ran in the Group 2 Sandown Mile in April, where he registered a three-quarters of a length win over Dream Eater.

Sent off the 11/8 favourite against a field that included Twice Over and Dream Eater, Paco Boy came with a strong challenge but faded in the final furlong to finish fourth behind Virtual.

[11] The Hannons felt that he had run below form, and it afterwards transpired that he was suffering from a broken navicular bone in the hoof that also affected him in the Sussex stakes group 1 where he finished second, beaten 2 1/2 lengths by Rip van winkle.

Although his Dubai conqueror Gladiatorus was sent off favourite, Paco Boy won by a length and a half from Ascot specialist Cesare, despite running across the track in the final furlong.

"[13] Due to his swift turn of foot, the Hannons decided to bring Paco Boy back in trip and run him in the July Cup over six furlongs at Newmarket.

[15] He then attempted to make amends for the previous year and win the Lockinge Stakes, which he did in extremely impressive style; coming to challenge on the bridle before quickening to lead in the final furlong.

[16] The race at Ascot featured a highly anticipated clash between dual Breeders Cup Mile winner Goldikova and Rip Van Winkle, who had also won the Queen Elizabeth II Stakes.

[18] Paco Boy attempted to get back to winning ways in the Group 1 Prix du Moulin, but was blocked half a furlong from home before running on again to finish fourth to upset winner Fuisse.

Held up near the back of the field as usual, Paco Boy ran on late down the straight to finish fourth behind Goldikova, who won comfortably.

[22] However, his new owners decided to run him one last time in the Group 1 Hong Kong Mile at Sha Tin where, despite being sent off the 2/1 favourite, he ran very poorly and finished last in a field of thirteen.
