Frankie Dettori will get the leg up on Toast Of New York for the first time in the next couple of weeks as Jamie Osborne steps up his stable star's preparations for the Dubai World Cup.

The four-year-old was a stunning winner of the UAE Derby at Meydan last year and having come within a whisker of claiming victory in the Breeders' Cup Classic at Santa Anita in November, he will return to Dubai next month as a major contender for the world's richest race.

Sheikh Joaan Al Thani's Al Shaqab Racing empire bought into the valuable colt, meaning the owner's retained rider Dettori will take over in the saddle from Jamie Spencer.

Dettori will partner Toast Of New York for the first time in a racecourse gallop at Kempton early next month.

"He went to Kempton on Tuesday and worked well and he'll probably go back the week after next, but we'll talk to Frankie and see what fits in with him," Osborne said.

"We're very happy with the horse at home. We put him through a fairly high intensity regime when he's building up for a race and he's in the middle of that at the moment.

"He's cantering every day, he'll have a couple more gallops at home and we'll keep moving forward with him."
