From record purchases to international stars, you sent us plenty of examples of the club’s most underwhelming signings.
But who were the most frequent suggestions? Scroll down and click through the pages to take a look at the names that most supporters mentioned, and some background as to why they failed to deliver at the Stadium of Light:
13. IGNACIO SCOCCO
Another striker who failed to deliver, Scocco’s signing got Sunderland fans excited - but he made only six appearances for the club and failed to find the net. Photo: Mike Hewitt
14. KEIREN WESTWOOD
The stopper arrived at Sunderland having garnered a fine reputation in the lower leagues. He failed to really establish himself on Wearside, making just 24 appearances over three seasons. Photo: Tim Keeton
15. THOMAS HELMER
A vastly-experienced German defender, Helmer looked to tick all the boxes required to play in the Premier League. He couldn’t quite do it at Sunderland though, making just two starts under Peter Reid. Photo: David Rogers
16. DANNY GRAHAM
Graham scored regularly at practically all of his previous clubs, but couldn’t deliver the goods at Sunderland. One goal in 42 appearances says enough about his spell at the Stadium of Light. Photo: Stu Forster
