Rivne Oblast, his first steps in football Kosovskyi started when he went to the first grade of school as it happened to be that near the school was also located a children-youth
sports school. Kosovskyi explained that his father worked as a driver in
Netishyn which is located in neighboring
Khmelnytskyi Oblast. When in Netishyn started to be built the
Khmelnytskyi Nuclear Power Plant, in 1984 Netishyn was granted the status of city and around that time the Kosovskyi family received a new apartment to which they moved. ==Club career==
