From memory, which can be suspect these days. over a mile the only horse I can think of that might beat Frankel was the great Brigadier Gerard.
Over a mile and a half then Dancing Brave, Secretariat, Sea the Stars, Bering, Montjeu and Peintre Celebre, Allez France at their best might all be in with a shout, particularly Dancing Brave.
Frankel's return to the winning enclosure on Saturday was one of those sporting moments that will live with me for a long time.
