After concluding a decorated playing career in 2014, Heinze wasted no time transitioning into management. He began his coaching career in Argentina’s top flight, taking the reins at clubs including Godoy Cruz, Argentinos Juniors, and Velez Sarsfield. In 2021, he briefly ventured into Major League Soccer with Atlanta United, though his time there lasted just six months.
His most recent role was as head coach of Newell’s Old Boys, the same club where he began his playing journey. His year-long stint at the Argentine outfit further deepened his managerial experience and tactical philosophy, which he now brings to the Premier League.
