There was pressure on Marcelino coming into this weekend, the 20th round of the LaLiga Santander season, but now that pressure has shifted onto Celta Vigo coach Miguel Cardoso after a 2-1 win for Valencia at Balaidos.
Celta Vigo had gone ahead thanks to Nestor Araujo towards the end of a wild first half, but second half strikes from Ferran Torres and Rodrigo Moreno turned the game on its head.
Araujo's goal came in the 40th minute, at the end of a first half that featured three shots on target for each side and plenty of saves from Ruben Blanco and Neto.
Neto had just spectacularly denied Sofiane Boufal with one of the saves of the season, but Celta Vigo took their lead from the resulting corner.
Valencia took control after the interval and substitute Ferran Torres netted the equaliser in the 71st minute, taking the ball down on his chest and then firing past the helpless Ruben.
It was another substitute who created the winner, as Kevin Gameiro played a perfect pass towards Rodrigo Moreno, who was able to turn into an empty net with six minutes remaining.
Valencia held on for what was just their fifth win of this LaLiga Santander season, a victory that moves them up to seventh in the table.
