The 2008 Torneo Descentralizado (known as the Copa Cable Mágico for sponsorship reasons) was the ninety-second season of Peruvian football. A total of 14 teams competed in the tournament, with Universidad San Martín defending their national title. The season began on February 17, 2008 and ended on December 14, 2008. Competition modus The season was divided into two tournaments; Torneo Apertura from February to July and the Torneo Clausura from July to December. Both tournaments had the fourteen teams play a round-robin home-and-away round for a total of 26 matches in each tournament. The winner of the Torneo Apertura qualified to the 2009 Copa Libertadores group stage and was eligible to play in the season final if they finished above 8th place in the Torneo Clausura. The winner of the Torneo Clausura also qualified to the group stage and was eligible to play in the season final if they finished above 8th place in the Torneo Apertura. A team that would've won both tournament was automatically season champion. If one of the tournament winners failed to place above 8th place, the other tournament winner would've been season champion. If both teams failed to finish above 8th place, the team that placed higher on the aggregate table–the summation of the points earned in both tournaments–would've been season champion. The two teams that placed last on the aggregate table were relegated and the best placed team–excluding the two tournament winners–qualified to the first stage of the 2009 Copa Libertadores. The second and third best placed teams on the aggregate table qualified to the 2009 Copa Sudamericana. Changes from 2007 Structural changes The number of teams was increased from 12 to 14. Due to the increase in teams, the tournament winners could finish in the top seven instead of the top six to play in the season finals. 1,170 minutes of game time was to be accumulated by players born on or after 1989 in the Torneo Apertura and Torneo Clausura. The amount for the Torneo Clausura was later reduced to 600. The minimum stadium capacity was increased from 4,000 to 5,000. Promotion and relegation Deportivo Municipal and Total Clean finished the 2007 season in 11th and 12th place, respectively, in the aggregate table and thus were relegated to the Segunda División. They were replaced by the champions of the Segunda División 2007 and Copa Perú 2007, Universidad César Vallejo and Juan Aurich.
