Ecuador have named a 24-man squad for their friendly fixture against the Netherlands on Saturday.
All nations participating in the FIFA World Cup, which gets under way in Brazil next month, are required to submit provisional squad lists by Tuesday, with those groups being trimmed to 23 players by June 2.
And Antonio Valencia headlines the Ecuadorian selection as the Manchester United winger prepares to compete in his second World Cup.
Valencia made four appearances as Ecuador reached the last 16 in Germany in 2006, eventually being eliminated by England.
Jorge Guagua, Segundo Castillo, Luis Saritama are the only other members of that team to be included in the squad for Saturday's fixture.
Uncapped duo Carlos Gruezo of Stuttgart and Armando Wila of Universidad Catolica have also been selected, boosting their hopes of being selected for the tournament in Brazil.
