Mainly a defensive midfielder with good positioning and skills,[1] he played for nearly a decade with Dinamo Minsk, also having abroad stints in the Netherlands (one year) and Spain; in the early 2000s, he embarked on a coaching career.
In his second professional season, he appeared 30 times and netted twice to help his hometown side win the only Soviet League in their history, edging Dynamo Kyiv by one point.
Zygmantovich made his debut for the Soviet Union on 28 March 1984, in an exhibition game with West Germany.
He represented the nation at the 1990 FIFA World Cup, scoring a goal against Cameroon (4–0, although in a final group stage exit) which turned out to be his last international game for the country.
Zygmantovich later appeared for Belarus in nine matches, his first being a 1–1 friendly draw with Ukraine in Minsk, on 28 October 1992.
