Other controversial events took place in 2006-2007. In October 2006, at half-time during a match against Boca Juniors in La Plata, Muñoz appeared in the dressing rooms, requesting to be able to talk to the referee and voice a number of complaints. The result was the suspension of the game by the referee, and a six-month reproof by the Asociación del Fútbol Argentino to the President of Gimnasia. Prior to the continuation of this game, several weeks later, some Gimnasia players complained that they had been pressed by nondescript visitors who wished that Gimnasia would allow a victory by Boca, so as not to benefit archrivals Estudiantes. In the outcry that followed, Muñoz was widely considered responsible for these events. Gimnasia went on to lose the game 1-4, after leading 1-0 at the time of suspension.
