Ace Impact and Hukum headline 15 Arc contenders

Ace Impact and Hukum are among 15 horses to stand their ground for the the Prix de l'Arc de Triomphe at Paris Longchamp on Sunday following the first forfeit stage.

French Derby hero Ace Impact is the clear favourite to provide trainer Jean-Claude Rouget with his second victory in Europe's premier middle-distance contest, following the success of Sottsass three years ago, but looks set to face a strong challenge from across the Channel.

The Owen Burrows-trained Hukum and Ralph Beckett's Westover look the pick of the British contingent, with both having been kept fresh since their titanic tussle in the King George at Ascot in July.

Michael Stoute's Bay Bridge and John and Thady Gosden's Free Wind, the potential final Arc ride for Frankie Dettori, also remain in contention.

Aidan O'Brien has left in Emily Dickinson, but on Sunday indicated she is likely to head for the Prix du Cadran instead, paving the way for his St Leger hero Continuous to be supplemented on Wednesday.

Continuous does not hold an entry in the Arc, but O'Brien did raise the possibility of supplementing the three-year-old at a cost of €120,000 in the immediate aftermath of his Doncaster triumph and the Ballydoyle handler is now preparing to add him to the field.

"It’s all about Continuous I’d say," he said on Sunday. "Everything looks good with him at the moment."

Irish hopes could also be carried by Sprewell from Jessica Harrington's yard.

Other contenders for the home team include Pascal Bary's Grand Prix de Paris hero Feed The Flame, last seen finishing second in the Prix Niel, and Simca Mille from Stephane Wattel's yard.

The latter has won twice and finished second twice from four visits to the track and was last seen breaking his Group One duck in the Grosser
