Two-time Tour de France winner Chris Froome will lead Team Sky in the Vuelta a Espana starting on Saturday.
Team Sky confirmed the Briton, 30, who won the Tour in July, in a nine-man team featuring Welshman Geraint Thomas and Ireland's Nicolas Roche.
Colombian Sergio Henao, Spain's Mikel Nieve and Belarusian Vasil Kiryienka will also support Froome.
The three-week race begins with a 7.4km team time trial from Puerto Banus to Marbella in Spain.
Froome will face competition from Giro d'Italia winner Nairo Quintana, 2014 Tour de France champion Vincenzo Nibali and 2009 Vuelta winner Alejandro Valverde.
Second to Alberto Contador in the Vuelta last year, Froome is aiming to become the 10th rider to win two Grand Tours in a season.
Froome, Thomas and Roche are the only riders from Team Sky's triumphant Tour de France line-up to figure in the Vuelta team.
Froome became the first Briton to win the Tour twice, following Sir Bradley Wiggins's triumph in 2012.
Sky team principal Dave Brailsford said: "It's been an unforgettable summer for us after winning the Tour de France for the third time, but it's important to move on quickly, realign our goals and focus on the new challenges ahead."
The Vuelta, the third and final Grand Tour of the season, finishes on 13 September in Madrid.
