After Paul Hartley brought in 17 new faces in the summer, Keith Curle added 15 more following his arrival in late September through to February before his departure from the club.
In total, 32 players have come through the doors at the Suit Direct Stadium this season whether by loan, permanent transfer or as a free agent.
And here we look at 11 of those players who have already since left the club:
5. Christopher Missilou
Missilou joined as a free agent under Keith Curle in November but would leave the club in January after falling out of favour. The midfielder made just five appearances. (Credit: Michael Driver | MI News) Photo: Michael Driver
6. Ellis Taylor
Taylor was sent back to Sunderland from his loan spell with his boyhood club after Keith Curle confessed to not knowing his best position. The youngster made just eight appearances after being signed on loan by Paul Hartley on the back of an impressive display in the pre-season fixture between the two sides.

7. Clarke Oduor
One of the more surprising exits came when Oduor was sent back to parent club Barnsley. Keith Curle struggled to guarantee Oduor regular game time which saw him leave the club in January just four months on from his arrival. (Credit: Michael Driver | MI News) Photo: Michael Driver
8. Chris Maguire
Maguire was signed by former manager Paul Hartley after the summer transfer window but was unable to make a single appearance for the club due to contractual issues. The former Sunderland man has since joined Scottish side Ayr United upon his return to football. Picture by FRANK REID Photo: Frank Reid
