What I like about him fromt his video is that he doesn't lose his confidence and shrink back because he wasn't winning the duels. It's great for a young player to be able to continually back himself to go up against one of the best defenders in the league.
I saw that game. Koulibaly indeed won most of the duels, but Kulusevski gave him a hard time. In the end he killed them for the second time last season. It was one of those games were Parma had a hard time and barely played on Napoli’s half.
