Godolphin\'s Frankie Dettori has insisted he has no plans to retire from racing despite failing to secure a ride in Saturday\'s Derby - the first time in 20 years. The former Derby-winning rider lost his status as Goldolphin\'s only retained jockey this year but said in comments published by the UK\'s Racing Post: \"I\'ve got at least five more years in me. I\'m only 41 and would challenge any jockey to a one-on-one.\" The Goldolphin stable is not fielding a runner in this year\'s race but Dettori has also lost out to Mickael Barzalona for the seat on Godolphin\'s only entry in Friday\'s Epsom Oaks, the filly Kailani. Goldolphin racing manager Simon Crisford described the rumours as a \"storm in a teacup\". \"Frankie is still hungry,\" he said in comments published by the BBC website. \"Nothing has changed - Frankie is still our senior rider but Sheikh Mohammed will decide who rides what, and he knows that.” Dettori, who now competes with Barzalona and Silvestre de Sousa for rides at Goldolphin, has produced 13 winners in his 92 rides this season. Kailani faces 13 fillies including juvenile Group One winner Maybe and Group Three Tattersalls Musidora Stakes scorer The Fugue plus emphatic Listed winner Kissed. From Arabian Business
