The duo both left the Stadium of Light on Friday evening having held the roles of Head of Football Operations and Head of Recruitment respectively since 2018.
Here, we take a look back at the signings made under their watch and evaluate whether their forays into the market were a success or not:
9. Luke O'Nien
A fine performer on the pitch, and a great ambassador for the club off it, O'Nien has become a vital part of Sunderland's squad. VERDICT: HIT Photo: FRANK REID 2019
10. Charlie Wyke
A regular under Phil Parkinson, the striker still divides opinion among the fanbase. Next season is a big one for him. VERDICT: THE JURY IS OUT Photo: FRANK REID 2019
11. Max Power
Captained the side for large parts of last season and has been a near ever-present since his arrival. VERDICT: HIT Photo: Frank Reid
12. Grant Leadbitter
While he may not have made the impact on the pitch that many would have hoped, Leadbitter's presence behind the scenes has been invaluable. VERDICT: HIT Photo: Frank Reid
