Dettori revels in Group 1 glory Frankie Dettori claimed his first Group One winner since his comeback and can look forward to riding one of the favourites for the Prix de l'Arc de Triomphe as Treve turned in a dazzling performance on a remarkable day of trials at Longchamp. Sandwiched between the victories of Japanese raiders Kizuna and Orfevre as the ante-post market changed almost minute by minute, Criquette Head-Maarek's diminutive-but-unbeaten filly will be aimed for France's greatest prize in three weeks time, as she was in a class of her own against her own sex in the Prix Vermeille. With a popular trainer and a show-stopping change of gear, Treve could be the kind of filly to gain a real following and a composed Dettori had no concerns when she was rather trapped off the pace on the rail for much of the mile and a half. Switched wide in the home straight, she quickly whittled down the advantage gained by Lady Cecil's high-class Wild Coco and won comfortably by a length and three-quarters. Dettori, who returned at the start of summer after serving the well-publicised drugs ban he picked up when riding in France, was cementing his partnership with Sheikh Joaan Al Thani and immediately embraced the owner. He said: "It's brilliant. She's the first decent horse I've ridden for a while, so it's great. "The Arc will be a different type of race, so I just hope I'm drawn on the fence so I can get some cover. It was always the plan to ride her like that as I knew she had a great turn of foot." Head-Maarek added: "She didn't do anything today, she's hardly breathing and she only raced for a furlong as she was held in. "She was a bit fresh today, so we should have some more to come in the Arc." The small matter of a supplementary fee should prove no issue to owner Sheikh Johaan al Thani.
