Scouting Report
Analyst's Take
Relentless tackler, steady carrying presence

Cornelsen's match data reveals a player built around defensive workrate, averaging over eleven tackles per game across ten international appearances — a figure underlined by a single-game peak of nineteen. He contributes consistently with ball in hand without dominating that phase, offering reliable metres and a high carry count that points to a workhorse role at the set-piece and beyond. His minute tallies and tackle numbers together suggest a lock trusted to stay on the field and absorb pressure across full contests.
