Gary Neville’s Valencia side suffered a derby defeat as they lost at La Liga’s bottom team, Levante.
Giuseppe Rossi, who played alongside Neville at Manchester United, scored the only goal of the game when he volleyed in from Juanfran’s long throw.
Valencia’s Sofiane Feghouli had a shot saved by Levante goalkeeper Diego Marino and later curled an effort wide.
Neville has now won only three of 15 La Liga games and Valencia are 12th, eight points above the relegation zone.
The 41-year-old former England international was appointed in December, on a contract until the end of the season, but has struggled in his first managerial role.
Valencia are on course for their worst league finish since they came 14th in La Liga in 1987-88 and are fewer points away from the relegation zone than a top-six place that would secure European football next season.
Indeed, Neville’s team face a vital match on Thursday as they look to overturn a 1-0 deficit when they host Athletic Bilbao in the second leg of their last-16 Europa League tie.
