Hector Gamarra, Denis De la Cruz and Fernando Pajuelo took over the club and became one of the most attractive teams of the Copa Perú.

His first major campaign was in 2005, when it ranked first in the National Stage representing Lima and reached the quarterfinals where they were eliminated by José Gálvez FBC of Chimbote.
