In 2005, the old Gimnasia stadium (known as El Bosque, the Forest) became suspended after incidents that took place during a decisive game against Newell's Old Boys. As president, he made the decision to play temporarily in the much-debated "Estadio Ciudad de La Plata" venue. However, that temporary move soon became de facto permanent, after he refused to comply with the various reforms requested for the old stadium by the CoProSeDe, the provincial organization in charge of security at sporting venues. Muñoz argued that the cost of making these reforms was “unsurmountable” (approximately 2 million Argentine pesos). This decision was resisted by many who demanded a return to El Bosque. After the end of Muñoz's mandate in 2007, the new management began finally the renovations; it is believed that Gimnasia y Esgrima La Plata should be able to use the old field some time during 2008.
