During his time at the Academy of Light, the former Birmingham City man has overseen a radical overhaul of the club’s playing squad with the Wearsiders focusing on their academy, and buying young players to be nurtured and blooded in the first team.
It is a strategy that has produced results, with Speakman providing a squad that Alex Neil managed to brilliantly turn into promotion winners following Lee Johnson’s under-achievement. However, with any recruitment strategy, there are pros and cons.
Indeed, Speakman has been criticised in some quarters for not providing Sunderland with enough depth, as evidenced by the injuries to Ross Stewart and Ellis Simms, leaving Tony Mowbray without any senior strikers for parts of last season, a problem that then impacted Mowbray’s replacement, Michael Beale.
Factors such as contract decisions, outgoing transfers, loans, managerial change, staffing structures, youth players, scouting, squad depth and the state of the Academy of Light all determine how Speakman and his team are judged.
Here, we take a look at the outgoing permanent departures sanctioned by Speakman since his arrival at the club – and attempt to analyse whether or not each case was the right decision.
Note that the list includes some who wanted to leave Sunderland alongside retirees and players whose contracts expired. The list does not include loan departures like Alex Bass and Joe Anderson or loanees who have returned to their parent clubs such as Joe Gelhardt, Frederik Alves and Callum Doyle.

1. Benji Kimpioka
Although provided Sunderland with some decent moments, there is no doubting that the talent of Sunderland's current attacking options way eclipse that of Kimpioka. (8/10 - a move that was best for all parties) Photo: FRANK REID 2021

2. Will Grigg
Unfortunately, for one reason or another, Will Grigg will likely go down as one of Sunderland's most underwhelming signings. It wasn't a surprise to see him leave when his contract finally expired. (8/10 - a move that was best for all parties) Photo: Stu Forster

3. Danny Graham
One of three retirees on this list. Given his performances in red and white, it was the correct call to allow the striker to call time on his career midway through his second Sunderland stint. (Another decision that needed to be taken for the good of the club 8/10) Photo: Lewis Storey

4. George Dobson
A player who struggled at Sunderland and remains in League One with Charlton Athletic. Not many Black Cats supporters were upset with his eventual departure.
