Former Central Coast Mariners boss Montgomery is the fifth man to take the job on a full-time basis since the late Ron Gordon took over Hibs in July 2019, following Paul Heckingbottom, Jack Ross, Shaun Maloney and Lee Johnson.
Over the years, Hibs have had 36 different full-time managers – but which ones have won the most games while in the Easter Road hotseat?
Only those managers who had 10 or more matches in charge have been considered.
