After 45 years in the lower leagues, Town had made a triumphant return to the pinnacle of English football and would take on the likes of Manchester United, Chelsea and Arsenal in the 2017/18 top flight.
It didn't seem as though the German centre back would be given the chance after five penalties however, as the Royals found themselves 3-1 up following Michael Hefele's saved spot kick.
But the Terriers turned it around, with Nahki Wells, Aaron Mooy and Schindler all converting from 12 yards and Liam Moore and Jordan Obita failing to convert their own chances.
