Valencia eased the pressure on coach Nuno Espirito Santo by thrashing high-flying Celta Vigo 5-1 to record their biggest win of the season.
Paco Alcacer opened the scoring at Balaidos after just 12 minutes, although Augusto Fernandez levelled midway through the first half as the hosts began to reassert themselves.
But Valencia captain Dani Parejo scored a wonder goal on the stroke of half-time to give the visitors a lead they did not deserve and then Alcacer struck again a minute after the break to put the visitors well in charge.
Parejo, with his second, and Shkrodan Mustafi heaped further misery on Eduardo Berizzo's men later in the half.
Valencia beat local rivals Levante 3-0 in their last league outing, but the fans in the Mestalla still called for Nuno's dismissal.
Supporters' frustration would only have increased with the 1-0 reverse against Belgian side Gent in the Champions League on Wednesday and the trip to Balaidos looked a daunting one for the boss.
The Galicians had secured a 3-2 win at Real Sociedad in injury-time last weekend and went into this game third in the table, having only lost one game all season, at home to Real Madrid.
But they fell behind early on when Parejo fed Alcacer in the area and the Spain international took one touch before dispatching the ball into the far corner.
Pablo Hernandez head home at the othet end two minutes later, but his effort was correctly ruled out for offside.
Celta kept putting pressure on their opponents, but could only force corners. They had a total of eight corners in little more than 20 minutes and finally made one count as Fernandez headed home from close range.
The hosts looked destined to go on to take the lead, but could not make the most of their many chances. Instead Valencia restored their advantage with just their second attempt on target, a superbly executed free-kick from Parejo.
Celta's sense of injustice was only compounded at the start of the second half, when an under-hit back pass from Jonny Castro allowed Alcacer to race in and slip the ball beyond Sergio Alvarez.
Celta refused to give up and were denied a goal by a matter of inches when Iago Aspas' shot struck a post and Valencia goalkeeper Jaume Domenech reacted quickly to prevent Nolito from pouncing on the rebound.
They suffered a killer blow four minutes later as this time Alcacer laid a pass on for Parejo to score his second.
The Valencia skipper then rounded off a complete performance by crossing for Mustafi to head Valencia's fifth, from just five attempts on target.
