Sergey Sergeyevich Frantsev (Russian: Серге́й Серге́евич Фра́нцев; born 17 March 1959) is a Russian professional football coach and a former player. He is the manager of Russian Amateur Football League club Kirovetz-Voskhozhdeniye St. Petersburg.
On 5 November 2015, Frantsev was named as manager of the Estonian Meistriliiga club Nõmme Kalju.[1] After finishing third both in 2016 and 2017 Frantsev and Kalju finally won the league title in 2018.[2] Kalju also won the pre season Estonian Supercup in 2019. The club's best result under Frantsev in European competitions was the third qualifying round in the 2016–17 UEFA Europa League, beating Maccabi Haifa on the way.[3] Frantsev was sacked on 25 April 2019 due to a poor start to the 2019 season.[4]
