Cercene upstages Zarigana while Eithical Diamond shines on momentous day at Royal Ascot for Willie Mullins

"These are just fantastic days, Jackie was just saying to me coming in here today 'just enjoy it', and then to have a winner on top that is the cherry on the cake," said Mullins.

Cercene gave jockey Gary Carroll and trainer Joseph Murphy a day to remember when bravely holding off French hotpot Zarigana to land the Coronation Stakes at Royal Ascot.

Billed as a clash between French 1,000 Guineas winner Zarigana and Owen Burrows' supplemented Falakeyah, it was the Irish outsider who stole the show to become the race's longest-priced winner at 33-1.
