Depor managed a strong 1-0 win over Sevilla on Saturday.
Lotina told Marca: “We earned this win by working for every second of the match.
“Sevilla is a big team, but we did not fear them. I do not remember Aranzubia making any great saves, or the ball hitting the woodwork.
“Despite the money they have spent in the summer, they did not dominate. We are strong defensively because everyone works hard.
“We asked the players to make up for last season with intelligence. We must keep our feet on the ground.
“If we start making mistakes, the problems will come.
“Everything that we manage is down to daily hard work.”
