Pietro Vierchowod (Italian pronunciation: ['pj??tro 'vj?rkovud]; born 6 April 1959) is an Italian former footballer who played as a defender, and a current manager.
He also represented the Italian national side during his career, and was most notably a member of the Italian squad that won the 1982 FIFA World Cup.
Widely regarded as one of the greatest Italian centre-backs of all-time, and one of the best of his generation, during his playing career he was nicknamed lo Zar ("the Tsar") because of his pace, defensive ability, physicality, tenacious playing style, and Ukrainian descent; he was the son of a Ukrainian Red Army soldier from Starobilsk.
