More from the Valencia fans blog I quoted earlier "Going back to the season 2007-08 Valencia was playing fairly well and than came the sacking of coach Quique Sanchez Flores and the appointment of new coach Ronald Koeman, who left PSV to join Valencia. This was supposed to be a match made in haven, only in turned out it was a match made in hell as Koeman broke the relationship with many Valencia veterans, made constant first team changes and Valencia was in the relegation zone and fighting to survive. The only thing that came out from the season was the surprise Copa Del Rey trophy.
Koeman was fired before the end of the season and was replaced with Valencia intern Voro who lead Valencia to 10th place finish."
