Joseph O'Brien feels Magician has plenty going for him as he seeks a second major success in America on Saturday night.

The Aidan O'Brien-trained four-year-old enjoyed his finest hour to date when collaring The Fugue to claim the Breeders' Cup Turf at Santa Anita in November.

The Arlington Million in Chicago is now the race connections turn to after a disappointing run in the King George VI And Queen Elizabeth Stakes at Ascot, where he was only sixth to Taghrooda.

"The ground is good and quick out there and it's a mile and a quarter, so we're hoping for a good run," O'Brien told At The Races.

"Quick ground is essential to him really and he hasn't had that this year.

"The ground was gone for him (in the King George) and I knew after a furlong I wasn't comfortable.

"We're hoping he can come back to that (Breeders' Cup) sort of form."
