Sevilla boss Eduardo Berizzo has said he will look for solutions to get his side out of their current dip in form, in which they have conceded nine goals in two games.
The Andalusian side were thrashed in mid-week by Spartak Moscow, conceding five and they conceded four as they were completely outclassed by Los Che.
Goncalo Guedes, who scored for Valencia last weekend against Real Betis, followed up that strike with a superb effort, sending his rocketing effort past Sergio Rico on the 43rd minute.
Italian striker Simone Zaza would then make it 2-0 six minutes after the break as he notched his eighth league goal of the season.
Santi Mina would the grab a third, before Guedes would secure his brace and Valencia’s fourth of the game in stoppage time.
The result saw Sevilla free-fall to two defeats in a row and concede nine goals in those games, having been thrashed by Spartak.
Berizzo, who spoke to reporters after the game has said that his main focus is on getting them out their poor run.
“I’m not worried about getting the sack, I’m worried about other things that are wrong. I worry about not finding solutions to problems. After a defeat like that everything is pessimism and I don’t have answers to immediate questions. We have to get stronger, keep our heads up and work. I have the most responsibility in defeat.
“The changing-room needed a good match, which we hoped this one could be but we ended up on the end of a rout. Football does that and you have to look at it that way. My intention is to look for solutions.”
The Argentine coach must now prepare his side for the Copa del Rey midweek game with Cartagena, before hosting in-form Leganes at the weekend.
