No panic over Authorized

Derby winner Authorized remains firmly on course for the Prix de l’Arc de Triomphe, despite Peter Chapple-Hyam admitting his string have been dogged by a bug in his yard.

The Newmarket handler has enjoyed a dream season, with Authorized’s Epsom heroics supplemented by a brilliant performance in the Juddmonte International and Winker Watson emerging as a leading contender for top juvenile honours.
