Guilherme Arana passed by the Mixed Zone after the important victory at the San Mamés in the first leg of the Copa del Rey Round of 16: 'It's a great result but nothing's decided yet. We have to change our attitude now because we've another game here on Sunday. We have to work because there are another 90 minutes in the cup, it will be a massive match to decide who goes through.'
The wing-back referenced the team's mental strength to push on when it seemed most difficult: 'Anything can happen, but you have to be concentrated and keep your cool. We conceded a goal but we recovered to score two more. You often do have to play against the same opponent a couple of times in a row and you always have to be prepared. Sunday will be a different game and we'll have to fight for it.'
