The horse is trained by William Knight at Newmarket, one of the most famous training centres in the world. Knight's yard has already sent out 28 winners this season, which tells you this is a stable in form and one that knows what it is doing. Trainers do not typically rush a horse to the track unless they believe it is ready, so the fact that Persazz is making its debut is a small signal of confidence in itself. Beyond that, the racecourse will tell us everything the paddock cannot.
