Alan Knill joined Boro as assistant to Chris Wilder in November 2021. 

A former Welsh international defender, Knill played for the likes of Halifax Town, Swansea City, Bury, Scunthorpe United and Rotherham United. He also had spells as manager of the latter three of those clubs, as well as Bury where he first worked with Wilder, who was his assistant. 

The roles were reversed when Knill became assistant to Wilder at Northampton in 2014, and after celebrating promotion from League Two with the Cobblers they also worked together for a hugely successful spell - including another two promotions - with Sheffield United.
