Ecuador goalkeeper Joan Lopez, who doubles as captain, says the team is prepared ahead of Tuesday's clash with Nigeria.
Nigeria play Ecuador at the Goiania Olimpico Stadium, Goiania Brazil, on Tuesday in their second Group B match.
Both teams won their first matches with Nigeria beating Hungary 4-2, while Ecuador beat Australia 2-1.
“We have all been working together within the national team for a year now in this cycle,” Lopez told FIFA.com.
“We all have an excellent understanding of each other and are prepared for whatever comes our way.”
The Nigeria – Ecuador clash will kick off at 9 pm Nigerian time on Tuesday.
