Leading the trio of hotshots will be Giro d'Italia winner Richard Carapaz who will try to make it two from two attempts for Movistar in 2019 before he takes his talents to the Ineos behemoth in 2020.
With Nairo Quintana, also moving on at the end of the year, and a slowly ageing Alejandro Valverde in the lineup, it is likely the true team leader will be decided on the road.
Added depth will come from promising youngster Marc Soler, Imanol Erviti, Nelson Oliveira, Jorge Arcas and Antonio Pedrero.
Carapaz is coming off a leg freshener at the Vuelta a Burgos, where he finished third, while Tour de France Stage 18 winner Quintana and Valverde will hope to have recovered after competing at the Tour de France.
Given that, it would be logical to assume the 26-year-old Carapaz has the inside line on Vuelta leadership with Quintana and Valverde hoping for high-quality rides in support.
Carapaz would also be motivated to bring a second career GrandTour win to Team Ineos which should secure him a future leadership position just behind Tour de France winner Egan Bernal.
The 2019 race will be the organisation's 40th consecutive appearance at the Vuelta, a streak started in 1980, natting it four overall victories, 12 podium finishes, 61 stage wins and 10 team classification triumphs.
