Kocherhin is a product of the Youth Sportive School ♯11 in Odesa and the FC Dnipro Sportive School. His first trainers in FC Dnipro were Volodymyr Knysh and Ihor Khomenko.[citation needed]
He made his debut as a substituted player in a second half-time for FC Dnipro in the match against FC Volyn Lutsk on 24 July 2016 in the Ukrainian Premier League and scored one goal.[1]
He scored a hat-trick for Zorya Luhansk in a 5-1 away win against Inhulets Petrove on 2 August 2021.[citation needed]
In January 2022, Kocherhin agreed to join Polish Ekstraklasa side Raków Częstochowa on a three-year deal, starting from 1 July 2022. Due to the Russian invasion of Ukraine, his contract with Zorya was suspended under new FIFA rules.[2] He was therefore able to join his new side earlier than planned and was officially announced as Raków's new signing on 26 March 2022.[3]
