Aidan O’Brien’s provides three of the five contenders in with a shout of being crowned Cartier Horse of the Year following the unveiling of the nominations.

The trio are joined by the Jean-Claude Rouget-trained Almanzor, who added to his French Derby heroics by claiming both the Irish Champion Stakes at Leopardstown and the Champion Stakes at Ascot.

O'Brien's mare Found was runner-up at Ascot after her brilliant display in the Prix de l'Arc de Triomphe, while King George-winning stablemate Highland Reel enhanced his claims with a stunning victory in the Breeders' Cup Turf on Saturday night.

The other two nominees for the prestigious equine award are the brilliant filly Minding and Roger Varian's stable star Postponed.

The seven other awards, which will be presented in a ceremony on Tuesday evening, have four nominees in each.

Found, Highland Reel and Postponed are joined by Limato in the Cartier Older Horse division, while Almanzor heads the Three-Year-Old Colt nominees along with 2000 Guineas winner Galileo Gold, dual Derby hero Harzand and The Gurkha.

Alice Springs, La Cressonniere, Minding and Quiet Reflection are the potential winners of the Three-Year-Old Filly award.

Limato, Quiet Reflection, Mecca's Angel and The Tin Man could be crowned Cartier Sprinter of the year.

Gold Cup winner Order Of St George headlines the Cartier Stayer division, with Quest For More, Sheikhzayedroad and Vazirabad the other nominations.

Caravaggio, Churchill, Mehmas and The Last Lion are up for Two-Year-Old Colt prize, with Lady Aurelia, Brave Anna, Rhododendron and Roly Poly the possible winners of the fillies' equivalent.

Harry Herbert, Cartier's racing consultant, said: "There has been brilliant racing throughout 2016.

"The nominations for the 26th Cartier Racing Awards reflect the wonderful horses who have raced in Europe and beyond this year.

"The Cartier Racing Awards are eagerly awaited and the evening of Tuesday, November 8 will be a thrilling event."
