Dettori wary of O'Brien threat Frankie Dettori remains wary of Aidan O'Brien's Investec Derby contenders despite the absence of dual Classic winner Gleneagles at Epsom. O'Brien has won the last three renewals of the Classic with Camelot, Ruler Of The World and Australia but does not appear to have a strong contender this time around with English and Irish Guineas winner Gleneagles taken out of the race on Monday. Hans Holbein and Kilimanjaro won their respective trials at Chester and Lingfield, but Giovanni Canaletto is likely to go off a shorter price than those two despite being beaten on his return to action at the Curragh. Dettori partners favourite Golden Horn for John Gosden and he respects the chances of not only the O'Brien runners but also stablemate Jack Hobbs, who he rode to finish second in the Dante behind his Derby mount. "He (Golden Horn) is favourite, we know what he's made of," Dettori told At The Races. "The same question keeps coming up. Will he stay? My gut feeling says yes, so it's fingers crossed now as his preparation has gone well. "I'm scared of Jack Hobbs, the horse has improved since the Dante and he stays well. "The Derby is the Derby but my horse won the best trial and won it convincingly. I have lots of faith in the horse. "There's 15 left in so let's hope we get a smooth run and see if we can win it." Of the O'Brien trio, Dettori added: " Their forte is that they are all good stayers so I'm sure they are going to make a race of it. "The Chester Vase winner (Hans Holbein) looked a good stayer. You can never dismiss Aidan O'Brien, he's a master and whatever he runs you have to respect."
