With the first three home in Epsoms Investec Derby all lining up again, it is a chance to get a second look at the Classic generation, this time on a galloping track that focuses on stamina rather more than agility and precocity.

Epsom winner Ruler Of The Worlds relative inexperience was outweighed by the brilliant ride he received that day from Ryan Moore, but the Irish Derby winner is likely to be the colt who has done best since that last run on June 1 and has come on again.

It is amazing what a difference four weeks in the middle of summer can make to a high-class three-year-old, and Ruler Of The World may have progressed as much or even more than either Libertarian or Galileo Rock, which would give him an excellent chance of becoming the 17th horse to complete the Anglo-Irish Derby double.

But Libertarian could well be the one in the field who is most suited by the Curragh.

He was all at sea on the adverse camber at Epsom, yet he flew late to snatch second place on the line, just 1 lengths behind Ruler Of The World.

On a track which is much more likely to suit his galloping style, the New Approach colt should be in his element and I select him to beat Ruler Of The World.

Sugar Boy, the winner of the Sandown Classic Trial in April, has solid place claims, though the tough Trading Leather might give him a run for third spot.
