Verhoeven vs. Hari

The 10 December 2016 bout against former world champion Badr Hari at GLORY Collision in Oberhausen, Germany, was considered a watershed moment for Verhoeven's career, with Hari being a very entertaining, albeit controversial fighter, who had been a dominant force in the kickboxing community, while also being taller (1.98 to 1.96 m) with a reach advantage over Verhoeven.
