Chacco Blue x Baloubet du Rouet sounds like the best combination of the century.

Father:

Chacco Blue, currently No. 1 in all stallion rankings, needs no introduction.

Mother:

His dam, Booguie Night, has already produced an 8-year-old mare at GP3* level. She was a CSI 145 mare ridden by Richard Breuil, and is a daughter of VDL Groep Urane de Talma, a major international winner in 160 ridden by Leopold Van Asten. They are the family of French Olympic champion Rahotep de Toscane.
