Schumacher made his Stevenage debut, in the opening game of the season, in a 2–0 loss against Notts County. He started in the next five matches before missing two matches due to a hamstring injury sustained during a 1–1 draw against Dagenham & Redbridge on 29 August 2015. It wasn’t until on 19 September 2015 when Schumacher returned to the starting line–up, in a 3–2 loss against Barnet. He then regained his first team place, playing in the midfield position since returning from injury. After serving a one match suspension, he scored his first goal for the club in a 2–1 defeat at Northampton Town on 24 October 2015. Two weeks later on 7 November 2015, Schumacher scored his second goal for Stevenage, in a 3–0 win over Gillingham in the first round of FA Cup. Twoeeks later on 24 November 2015, Schumacher scored his third goal of the season, in a 2–1 win over Bristol Rovers. However, during the match, he tore his anterior cruciate ligament, resulting in him being sidelined for nine months, therefore missing the remainder of the 2015–16 season. By the time he suffered an injury, Schumacher finished the season, making eighteen appearance and scoring three times in all competitions.
