Royal Anthem is a 4 to 6 chance with Coral to beat Daylami in a match bet in an intriguing clash for the Esat Digifone Irish Champion Stakes next Saturday.
Daylami is an 11 to 10 chance with Coral to confirm his three-quarters-of-a-length Coronation Cup superiority over Henry Cecil's impressive Juddmonte International Stakes winner at Leopardstown.
The head-to-head bet will be void if either does not run, and is determined by which horses finishes ahead of the other regardless of who wins the race.
"Royal Anthem versus Daylami is a clash of heavyweight proportions, with Royal Anthem our favourite to confirm himself the top older horse in training in Britain, and maybe even the world," said Simon Clare, Coral's spokesman.
