Sai van Wermeskerken played all the first 22 games for Zwolle since the start of the 2020-21 league season full time. But he got injured during the training on 15 February. It turned out to be a rupture of the anterior cruciate ligament in his right leg.He is clearly an important part of the team. The data site OPTA has only three players in the Dutch first division who statistically won more balls than van Wermeskerken this season. His departure will have a big impact on the team.
In his second season with the club, he has started all 22 games, mainly at right back. He has recorded three assists. In January of this year, he signed an extension for two years till Summer 2023 to his current contract which expires at the end of this season.
