New Espanyol coach Javier Aguirre said he faces a race against time to avoid relegation but believes his squad is good enough to avoid the drop.
Aguirre, appointed on Wednesday, replaces Mauricio Pochettino, who left by "mutual consent" on Monday with Los Pericos rock bottom of the Primera Division, having taken only nine points from their opening 13 games.
The Mexican said it was vital that his new team began picking up points immediately - starting with his first game in charge at fellow strugglers Granada on Sunday.
"We are going against the clock," Aguirre said. "There are 25 games left, 75 points, and we must make up the ground we have lost.
"We all want to play good football with the resources we have here. First we must analyse where we are and motivate the players to move forward, starting with Granada. We need a good result.
"I have a deep respect for Mauricio Pochettino and the work he has done in his four years, but I want to move on from the past and start from zero."
The former Mexico and Atletico Madrid boss, 53, said the situation was similar to the one he had faced when saving Real Zaragoza from the drop two seasons ago.
"It seems similar to me, with institutional difficulties but with fans who want to get back behind the team and a quality squad," he said.
"For various reasons, the team is not where it deserves to be. It is an emergency situation, but there is time, willingness and motivation, the things I want to instill in the players."
He urged supporters and players to make their Cornella stadium "a pressure cooker, with all the fans with the team", adding: "The people will return to the team if they see it getting stuck into La Liga.
"I like to play well, to win, to please people. But if we need to roll up our sleeves, I am not afraid of anything. This team can save itself."
With Espanyol a reported €135 millon in debt and up for sale, Aguirre suggested it was more likely that he would be giving promising youngsters a chance than spending big in the January transfer window.
"This club has a very good cantera," he said. "If we need to throw someone in, we will, both because that is the policy here and because I like doing that."
