Australian superstar So You Think is in work under the care of Irish training wizard Aidan O'Brien.

So You Think, now majority-owned by Coolmore, arrived at the Irish breeding giant's famous Ballydoyle stables earlier this month to be set for a European campaign.

The two-time Cox Plate winner raced in Australia out of the stable of legendary trainer Bart Cummings for high-profile owner, the wealthy Malaysian businessman Dato Tan Chin Nam.

But Dato Tan sold a controlling interest in the stallion for an undisclosed sum.

The deal to buy into the son of the Coolmore sire High Chaparral was finalised after the horse's brave Melbourne Cup placing in November.

So You Think finished third to Americain in what turned out to be his only defeat during the Melbourne spring carnival - and his Australian farewell race.

"He is in light work and by all reports Aidan O'Brien is very happy with him," Dato Tan's Australian-based bloodstock and racing manager Duncan Ramage said.

Ramage said he expected So You Think would have few issues settling into his new environment.

"I would imagine the conditions he is experiencing are not too dissimilar to what he was used to when he was a young horse in New Zealand," Ramage said.

"And while he was in Australia he raced mainly out of Melbourne and he spelled in the (NSW) Southern Highlands.

"He hasn't suffered extreme weather conditions throughout his life so there is the potential for him to have less problems than other horses might have trying to acclimatise."

So You Think will begin his career with O'Brien already firmly established among the world's superior thoroughbreds.

Besides being rated the world's best stayer in the 2010 World Thoroughbred Rankings, So You Think also stands alongside Ballydoyle stablemate Rip Van Winkle as the leading middle distance horse on the planet.

Afforded a 126 rating, So You Think will make his European debut as Australia's highest-rated horse since the rankings began in 2002.

In early betting on major European flat season races, So You Think occupies a lofty position in charts on the Eclipse Stakes and King George VI & Queen Elizabeth Stakes in England and the Prix de l'Arc de Triomphe in France.
