Sergio Nichiporuk Kulik (born 24 February 1957) is a retired Paraguayan nationalized Chilean football player and manager who played as a striker.
Nichiporuk began playing football in the youth teams of Paraná. In 1975, he moved to the capital Asunción, where he made his professional debut with Nacional at the age of 18.[1] Nichiporuk also played for local rivals Presidente Hayes and San Lorenzo, before Ñublense manager Manuel Rodríguez Vega signed him in 1980.
After several seasons playing in the Chilean leagues with Ñublense, Santiago Wanderers and Iquique, Nichiporuk moved to Spain. In January 1983, he joined Mallorca where he made 15 appearances for the club during the 1982–83 Segunda División season.[2] [3] [4]
Nichiporuk joined Magallanes during 1984, but suffered a broken leg which limited his ability to play over the remainder of his career. After a spell with La Serena in 1986, he moved to Mexico to join Atlante F.C. where he made six appearances for the club during the 1987–88 Primera División season. He returned to Chile and finished his career with Lota Schwager, scoring 12 goals during the 1990 season.
A few years after retiring from professional football, Nichiporuk began coaching Tercera División side Municipal Las Condes. In 1995 he began his professional coaching career with Cobresal. He has led Cobresal on several occasions, winning promotion to the Primera División in 1998, and leading the club to a famous victory over Antofagasta on his Clausura 2006 debut.[5] Nichiporuk led Santiago Morning to the 2000 Copa Apertura Final, losing 2–1 to U. de Chile.[6] He also won promotion with Puerto Montt in 2002.[7]
