I'd like to see more Kazachenkov too, but although he and other youngsters had some playing time, I guess it was due to covid/injuries. Now Komarov and Tkachev returned to the bench.
Speaking of youngsters, I wonder why Murashko, the most promising player in Loko's youth team, has yet to be invited in the senior team. He is arguably a lot more talented than Kazachenkov IMO.
