A colt by Frankel will be the first of the champion's progeny to be offered at public auction at the inaugural Goffs London Sale.

The colt is for sale on Monday along with his dam, Crystal Gaze who is expecting a second foal by Frankel next year.

Crystal Gaze has already produced the classy sprinter Spirit Quartz as well as Saturday's Epsom Dash winner Caspian Prince and the pair are expected to sell for a seven-figure sum.

The colt will be sold by Tweenhills Stud as agent.

"He is a very handsome colt with huge presence and great action. He has what I would call a typical Frankel temperament in that he knows he is special and really owns the show," Tweenhills' owner David Redvers said.

"At this stage he looks like a speedy type, which is no surprise given his mother has bred some excellent sprint winners."
