Ole reports that 'El Pelado' threw in the towel following his team's 1-0 reverse at the hands of Tigre, which left the Bajo Flores giants in 11th place after the same amount of games. Directors attempted to change the trainer's mind, but Diaz was insistent as he told them, "this decision is not up for discussion."
Diaz was greeted as a returning hero by Cuervo fans in 2010, when the trainer returned to the club in which he had lifted the 2007 Clausura title. Despite bringing in a host of new faces however the club struggled for consistency and could not fight in the upper reaches of the table in either championship.
The 51-year-old also had several run-ins with new president Carlos Abdo, threatening to resign two weeks ago following speculation that Nestor Gorosito was talking to the chief.
Speculation has started immediately on who will replace Diaz, with polls suggesting fans are content with his decision to quit. Former Estudiantes Copa Libertadores winner Alejandro Sabella has emerged as the front-runner and supporters' choice, while 'Pipo' Gorosito and Avai's Brazilian tecnico Silas have also been mentioned as possibilities.
