Unbeaten colt Geoffrey Chaucer is in line for a tilt at the French 2000 Guineas after starring in a team of more than 40 horses worked by Aidan O'Brien after racing at the Curragh on Sunday.

The three-year-old son of Montjeu won a Leopardstown maiden and the Beresford Stakes at the Curragh as a juvenile and O'Brien is considering a return in the Poule d'Essai des Poulains at Longchamp on May 11 or a race at Leopardstown on the same day.

"Geoffrey Chaucer is very much in the picture for the French Guineas. He's showing a lot of speed for a Montjeu," O'Brien said.

"I was thinking of running him at Navan on Saturday, but I was happier to come away here and he'll either start off in the Derrinstown Stud Derby Trial or the French Guineas on the same day."

Ascot Gold Cup hope Leading Light is due to kick off his season in the Vintage Crop Stakes at Navan while American import Verrazano also delighted his trainer ahead of a likely trip to Berkshire in June.

"The plan is still to start Leading Light off in the Vintage Crop at Navan, then it will be the Saval Beg Stakes at Leopardstown and the Ascot Gold Cup," O'Brien said.

"I was very happy with Verrazano today. His target is the mile race at Ascot (Queen Anne Stakes)."

In all O'Brien put 27 three-year-olds and older horses through their paces, while 15 two-year-olds were divided into three groups.

The much-vaunted Australia was not part of the team working at the track but O'Brien confirmed both he and stable companion War Command were on target to line up in the 2000 Guineas at Newmarket on May 3.
