Wrexham have a wealth of options in midfield, hence the club’s decision to let Andy Cannon – back from almost a year out with an ACL injury – spend the rest of the season at Burton Albion.
It is the same with back-to-back-to-back promotion heroes Paul Mullin and Elliot Lee who joined Bradford City and Doncaster Rovers respectively on loan.
But the final pieces were more of a jigsaw puzzle, with forward and wing-back options explored.
After Saturday’s win over Sheffield Wednesday, Parkinson stated Ryan Hardie would only be allowed to leave if they could find a replacement for the Scot.
Parkinson watched Sidiki Cherif in action for French club Angers, although the 19-year-old joined Turkish giants Fenerbahce on an initial loan deal, with the move to be made permanent in the summer.
But once the first domino fell, Wrexham’s final business swiftly fell into place.
The club agreed deals with Barnsley for Keillor-Dunn and Sheffield Wednesday for Cadamarteri – paving the way for Hardie to head to Huddersfield Town on loan.
Keillor-Dunn and Cadamarteri will now compete with the likes of top scorer Kieffer Moore, in-form Sam Smith and fit again Jay Rodriguez for game time.
At wing-back, James McClean’s departure to hometown club Derry City opened up the possibility of a new wide option being recruited.
But while they did not add to that department, Parkinson does have options.
Liberato Cacace and Issa Kabore are both fit again and started together for the first time in almost three months in the win at Hillsborough.
He also has Ryan Barnett and Ryan Longman at his disposal, while midfielder George Thomason has slotted in at left wing-back admirably at times this season.
Elsewhere, it was a case of trimming the numbers and increasing the game time of fringe players, as evidenced by the loan switches of Mo Faal and Harry Ashfield to Cheltenham Town.
Jacob Mendy also secured a permanent switch to Peterborough United who also terminated the loan of Tom O’Connor, with the Irishman returning to Wrexham as he recovers from a hamstring injury.
