Valencia manager Ernesto Valverde said that Saturday's 4-3 defeat to Sevilla will be his final match in charge of the side.
Defeat at the Sanchez Pizjuan meant that Valencia missed out on qualification for the Champions League as Real Sociedad's 1-0 win at Deportivo la Coruna saw them clinch fourth place.
"It is true that this has been my final game with Valencia," he told a press conference.
And the 49-year-old blamed the lack of institutional security at the club since the resignation of president Manuel Llorente in April for his decision to leave.
Llorente was immediately succeeded by Federico Varona, however his reign lasted only two months with incoming president Amadeo Salvo set to be elected next week.
"We were close to an agreement and then the president resigned and the events of the last few days came about.
"I have seen three projects in these months: Llorente's one, Varona's one and Salvo's one and there was only one that I valued."
Valverde, who has only been in charge at the Mestalla since December, has been linked with a return to Athletic Bilbao who he managed between 2003 and 2005.
However, he insisted that he has not yet reached an agreement to take over the Basque side.
"It is inevitable that people will think that my exit is due to an agreement with another club, but it is not like this."
