Last season, the Scotland international ranked among the best stop-stoppers in the Championship. His contributions were key to David Wagner's side producing a run of form that culminated in a spot in the play-offs.
Gunn's form this season hasn't been where it was last term. It has been a season wrapped in inconsistency, injury and uncertainty. Statistics involving the overall performance of City's goalkeepers have gained real traction on social media as the campaign has developed.
One statistic to measure goalkeeping performance is post-shot expected goals minus goals allowed. In layman's terms, it is a metric that uses expected goals to measure how likely a goalkeeper is to save a shot. City rank at -9.
