Sevilla midfielder Denis Suarez says they must not dwell on their domestic form slide.
Sevilla meet Borussia Monchengladbach tonight in the Europa League.
"It was a painful loss," Suarez said of defeat to Real Sociedad. "To concede a last-gasp goal is hard to digest.
"But we have to put this defeat behind us and react immediately.
"We have an important game coming up and we need to be fully focused."
