Aidan O’Brien is chasing a fourth consecutive Epsom Derby success and, while he may not have a stand-out performer in this afternoon’s feature, the Ballydoyle trainer may be able to extend his record with the strong-staying Hans Holbein.

There we were all ready to put up Dermot Weld’s Zawraq as the most likely winner of this afternoon’s Investec Derby at Epsom and the horse goes and suffers a setback.

Hans Holbein leapt into the picture for the Investec Derby when giving trainer Aidan O’Brien a welcome turn of fortunes with an all-the-way success in the MBNA Chester Vase on the Roodee yesterday.

Hans Holbein bids to give Aidan O’Brien a third successive triumph in the MBNA Chester Vase and his sixth in all when facing five rivals on the Roodee tomorrow.
