British bookmakers have reported significant money for the Aidan O'Brien-trained Gleneagles who is now favourite to win the 2000 Guineas.

Fourth on his racecourse debut, the Galileo colt finished his juvenile campaign with a third in the Prix Jean-Luc Lagardere at Longchamp in October after he was demoted from first for causing interference.

He had previously taken Group One honours in the Vincent O'Brien National Stakes at the Curragh.

Ladbrokes cut the Coolmore-owned runner to 4-1 for the season's first Classic on May 2 after as much as 8-1 was on offer at the start of this week.

"It's an interesting time of the year to be seeing support for a Ballydoyle Guineas contender. The price is in free-fall across the betting industry and Gleneagles has emerged as the clear Guineas favourite in next to no time this week," a spokesman said.

Betfred also went 4-1, having initially been 5-1 from 6-1.

William Hill mirrored that move, saying there was a strong flow of money for the colt while Coral firmed him from 6-1 to 9-2.
