After Uruguay suffered a heavy defeat to Argentina, La Celeste followed that with a loss to Bolivia, and the captain concedes it has been a difficult time for his national side.
In a match that saw little defense from La Celeste, which was without its captain, Lugano, Bolivia's Carlos Saucedo helped himself to a hat trick within the first hour. Oscar Tabarez's charges now find themselves in fifth place out of nine in the qualifying group and the 31-year-old center back says Uruguay is going through a difficult spell.
"What do you want me to say?" Lugano told reporters. "Results are not given. It's a rough patch.
"We created goal situations, but another amazing thing is that every time our opponents come forward, it was practically a goal."
Uruguay will travel to Poland next month for an international friendly, where Lugano could be in contention to start for the South Americans, but he hopes they turn around their form quickly.
"I want to believe this is just a stage," Lugano said. "One where, incredibly, everything went wrong."
