Marcel Theunissen

Marcel Theunissen is an openside flanker with South African franchise the Stormers. Born on 9 June 1999, he is among the more experienced operators in the back row, recognised for his high work rate at the breakdown and his ability to carry effectively in the wider channels. Theunissen's game blends the disruptive defensive qualities of a specialist openside with a useful attacking dimension. He competes hard for turnover ball, contributes heavily to the tackle count and offers himself as a link option in the team's expansive attacking structure, providing continuity between phases. Within the Stormers' setup he serves as a busy, all-action forward whose value is measured in the volume of involvements across both sides of the ball. His mobility allows him to influence play beyond the tight exchanges, while his breakdown work helps secure the platform from which the side launches its attack. A seasoned campaigner in the South African system, Theunissen brings experience and reliability to a competitive back-row department, and remains a dependable contributor to the forward effort.
