Leading French jockey Maxime Guyon has been appointed retained rider for the Wertheimer brothers replacing Olivier Peslier.
It was revealed earlier this month Peslier would not be kept on to ride for Wertheimers in 2015 following a hugely successful 12-year association.
During that time, Peslier partnered the incomparable mare Goldikova to a staggering 14 Group One victories, including a hat-trick of successes in the Breeders' Cup Mile.
Guyon has secured multiple Group One victories already in his relatively short career, during which he has principally ridden for legendary French trainer Andre Fabre.
The jockey has signed a four-year contract with the Wertheimers.
"It is correct that Maxime will ride for us from next year and, of course, we are very happy," Pierre Yves-Bureau, racing manager for the owners, said.
"We hope it will be a very good partnership in the coming years."
