won both tournaments of the season, they were automatically declared 1985 champions. Universitario de Deportes returned to the top of Peruvian football in 1987. As in 1985, Universitario began the season by winning the Regional Tournament, which put them in the season final to face off the winner of the Descentralizado for the national title. The Descentralizado went to their classic rival, Alianza Lima which meant the season final would be contested as another edition of the Clásico. Also, both Universitario and Alianza Lima reached the final with seventeen first division titles under their belts. The defining derby was won by Universitario with a single goal by Fidel Suárez, overcoming the tie they had in the most Peruvian titles. In 1990, with the arrival of Fernando Cuellar as coach, Universitario de Deportes won the First Regional Tournament of the season, automatically advancing to the season final where they faced Sport Boys, winner of the Second Regional Tournament. The mid-nineties (1992–1997) In the year 1992, the national championship regulations were generally amended again by dropping the regional tournaments and returning to a similar system before the 1980s where the clubs would first play in a league and subsequently advance to the Liguilla. The club won the title a week before the final round, after defeating CD San Agustín 4–1, with goals two goals from Ronald Baroni and the remaining coming from César Charún and José Luis Carranza. With Sergio Markarián in charge of the first team, la U defended its title in 1993, achieving a new bicampeonato for the club. The defining match that gave Universitario its twenty-first title was a 3–0 over San Agustín; two goals were scored by Jorge Amado Nunes and one by Roberto Martinez. This was the fourth time in the club's history that it won back-to-back titles. The treble (1998–2000) By winning in 1998, 1999, and 2000, Universitario won their first treble or Tricampeonato. The 1998 title was won under Oswaldo Piazza, Miguel Company and Roberto Challe led the club to the other two titles. It was the third Peruvian team to do this; the first being in the amateur era won by Alianza Lima and the second in the early nineties by Sporting Cristal. It was also during the 2000 season that they were the second Peruvian club to win an Apertura and Clausura in a single season; the first being Alianza Lima in 1997.
