Most people hold the Spanish side as favourites, but the Chilean coach does not agree.
“We are playing at a high level again but we do not feel like the favourites, because our opponents are one of the greatest teams in Greece and one of the best in Europe,” he said during the pre-match press conference.
He continued: “A good result will be to win. If we can win without conceding a goal, even better.
“However, there are 180 minutes of football to be played and in the knockout round, anything can happen. One goal will not be decisive.
“It would be a mistake just to think about keeping a clean sheet. We must think about winning and if possible, we want to win in style.”
