Last year's Hong Kong Vase hero Ange Gabriel has been nominated by trainer Alain de Royer Dupre as one of the three main dangers to the Aga Khan's super colt, Dalakhani, in the Prix de l'Arc de Triomphe at Longchamp on Sunday. When asked this week on British television which horses constituted the main threats to Dalakhani, de Royer Dupre replied: 'Doyen. I think Doyen is a very good horse. We also have Ange Gabriel and High Chaparral to beat.' Eric Libaud, trainer of Ange Gabriel, says the high-class grey will travel to Longchamp tomorrow and stay overnight at the picturesque Parisian racecourse. 'Although he is well travelled, he can find his journeys still a bit stressful and we wish to take no risks with him,' Libaud said. The Prix Foy (Gr 2) winner was the best-backed horse in pre-post Arc betting yesterday and is now at 8-1 (in from 10-1) for Europe's most prestigious race. De Royer Dupre said he did not want the ground to be too soft for Dalakhani. 'He can run on the soft. He won at Saint-Cloud as a two-year-old on very soft ground, but I would prefer good ground or firmer for him,' he said. The ground at Longchamp has dried out overnight and measured 3.0 (good) on the penetrometer scale compared to 3.3 (good to soft) on Tuesday. However, Paris welcomed its first rain for three weeks yesterday, much to the delight of clerk of the course Gerard Grandchamp. 'The rain has come at the right time and hopefully conditions should prove ideal come Sunday,' he told the Press Association. Doyen will be tackling Group One company for the first time. 'I hope he has improved enough to get his revenge on Dalakhani and I hope the pace of the race will be stronger than when he was beaten by him in the Prix Niel,' said Doyen's trainer, the renowned big-race master Andre Fabre. Sunday's big-race field was reduced to 19 following the defections of Brian Boru and Mer de Corail at the last acceptance stage. Dalakhani, coming off a good workout at Chantilly on Tuesday, and Doyen lead the home defence. The French squad includes Dalakhani's stablemates, Shakanndi and Diyapour (his usual pacemaker), plus Ange Gabriel, Ana Marie, Bright Sky and Policy Maker. The British acceptors are Mubtaker (Marcus Tregoning), Bollin Eric (Tim Easterby) and Kris Kin (Sir Michael Stoute), while Irish stables are well represented, with High Chaparral heading five entries from the Aidan O'Brien yard. The others are Black Sam Bellamy, Dalcassian, Yesterday and Fontanesi. John Oxx's Alamshar - left in by the Aga Khan in case of unforeseen problems with Dalakhani - and Dermot Weld's Vinnie Roe complete the Irish septet. Rounding off the foreign entries is Dai Jin. The German Derby winner, who reportedly worked well in Cologne on Sunday, is expected to be ridden by Olivier Peslier.
