Hierman Barkouski joined Piast Gliwice on a loan basis for the 2025/2026 season. The club has an option to purchase the player from Puszcza Niepołomice. Barkouski, a Belarusian striker, previously played for Dinamo Brest before joining Puszcza Niepołomice in January. He played 15 times in Ekstraklasa, scoring three goals and providing three assists, along with one goal in the Polish Cup. Puszcza Niepołomice was relegated to I liga, but Barkouski will not play there, at least for now.

Piast Gliwice is reportedly interested in signing Hierman Barkouski. The player, who transferred from Dynamo Brest to Puszcza Niepołomice, showcased impressive performance despite the team's relegation, having scored four goals and provided three assists in seventeen matches. Piast Gliwice is contemplating a move for him. The club has been on the lookout for a new striker following their decision to part ways with two forwards, Maciej Rosołek and Fabian Piasecki, and has already brought in Adrián Dalmau from Korona Kielce on a free transfer. Barkouski, who had been linked with Raków Częstochowa earlier in the year, has drawn Piast's interest, and negotiations might commence soon.
