His riders included Frenchman Laurent Jalabert and Swiss Alex Zülle; both dominated the Vuelta a España, each winning the general and other classifications.

Saiz's next riders included Spaniard Abraham Olano, Igor González de Galdeano and Joseba Beloki.

During the turmoil of the Festina affair during the 1998 Tour de France Saiz withdrew the ONCE-Deutsche Bank team.

Richard Virenque's lawyers depended on a clause in the UCI's rules, number 1.2.048, which says that tour organisers must say at least 30 days before a race whom they wished to admit.

Saiz was cleared of damaging public health and managed a restaurant and wedding catering business in his home region of Cantabria for several years.
