'I wasn't aware of how far clear I was. It's surreal to have won this race, I can't believe it'

Serpentine produced an extraordinary performance to upset the favourites and give Aidan O'Brien a record-breaking eighth Derby success, obliging at odds of 25-1. 

Pushed into the lead by Emmet McNamara in the early stages, Serpentine was not for catching rounding Tattenham Corner, with the likes of English King, Kameko and Mogul left floundering.

Khalifa Sat, a 50-1 shot, was second with 66-1 chance Amhran Na Bhfiann in third. Kameko, the 2,000 Guineas winner and 5-2 favourite, finished fourth under Oisin Murpy.

McNamara said: "I think I got a little bit of a freebie really. I had a huge amount of confidence in the horse having spoken to Aidan during the week, he said he thought the horse would stay a mile and six furlongs well.

"He told he to give him a breather around the six-furlong mark and then to keep building to that winning post because the horse would keep going, thank god he was right. 

"I couldn't see a thing around me and I didn't really want to be looking, so I wasn't aware of how far clear I was. It's surreal to have won this race, I can't believe it."

O'Brian, who celebrated a Classic double at Epsom following Love's decisive victory in the Oaks, said: "It's unbelievable really, we always thought he would stay very well.

"He won at the Curragh last week over a mile and a quarter and Wayne [Lordan] said he galloped right through the line and he couldn't pull him up. I am delighted for the owners as this is obviously another Classic-winning homebred by Galileo."

Following the race Paddy Power introduced Serpentine at 25-1 for the Prix de l'Arc de Triomphe, while Betfair Sportsbook cut the winner into 9-2 (from 16) for the St Leger.
