Ahead of the 2017–18 season, Compper suffered a calf injury during the club's pre–season tour. Despite returning to training from injury, just in time for the league started, Compper, however, found himself on the substitute bench, as he was fallen behind Willi Orban, Dayot Upamecano, Ibrahima Konaté and Stefan Ilsanker. This was also combined with a strained relationship with Manager Ralph Hasenhüttl. By the time of his departure, Compper made three appearances for the side in the first half of 2017–18 season.
