Top Serie A scorer Edinson Cavani, a substitute in Uruguay's disappointing 1-1 draw at home to Paraguay on Friday, was named instead by coach Oscar Tabarez on Monday to partner Luis Suarez up front.
"We need to improve a lot in what the team does when they take possession of the ball," Tabarez told a news conference in Santiago following Uruguay's last practice on Chilean soil.
"We've committed a lot of defensive errors that cost us points. A performance often is related to results [and] a positive result is what can change everything at the moment," said Tabarez.
"We need points urgently because we are among several teams fighting for the fourth and fifth place," Tabarez said.
Chile, looking to recover from a run of four defeats including Friday's 1-0 loss to Peru in Lima, are just outside in sixth place with 12 points.
