Deniz Undav Says Data-Driven Training Treats Players Like Robots

He warns that laptop-prescribed, one-size-fits-all fitness plans can raise injury risk by ignoring players’ individual habits.

Overview

  • Undav, speaking to the Bundesliga-Magazin on Thursday, Aug. 27, 2026, said data analysis benefits football but that coaches now look at laptops too much and treat players like machines.
  • He argued that uniform training prescriptions can clash with a player’s past habits or cultural background and cited the risk that unfamiliar exercises can lead to injuries within weeks.
  • Undav made the remarks as a general critique rather than a rebuke of VfB Stuttgart, noting that the club already makes individual accommodations for him.
  • The 30-year-old striker is VfB’s new captain and a German national-team player who said he discusses tactical ideas with head coach Sebastian Hoeneß and plans to move into coaching after his playing career.
  • The comments have attracted media attention but no formal reply from VfB, the Bundesliga, or club sports-science staff so far, and they feed a broader debate over how to balance data-led load monitoring with individualised player care.
