Aidan O'Brien's So You Think strengthened his position at the head of the market for the Dubai World Cup at Meydan on Saturday evening after being handed stall four at the draw ceremony for the richest race in the world.

The giant Australian import is now a 5-2 chance (from 3-1) with Paddy Power after faring much better than one of his main market rivals, Game On Dude, who will break from the widest stall of all in 14.

Japanese challenger Smart Falcon, the second-favourite, is positioned next to So You Think in stall five.

Of Godolphin's four challengers Monterosso fared best in stall eight with Capponi, Prince Bishop and Mendip in 11, 12 and 13 respectively.

Marco Botti`s Planteur will break from stall six while last year's runner-up Transcend will have to overcome stall 10.

"So You Think has the perfect draw, the best form in the book, and will now go to post as a heavy favourite for the world's richest race. Game On Dude, by contrast, will find it very tough to win from stall 14," said Simon Clare, Coral spokesman.

Smart Falcon was also eased to 5-1 from 4-1 by Coral following reports that he had not travelled over from Japan particularly well.
