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:
5. WILL GRIGG
Another popular suggestion was Grigg. Signed in a £3million deal on January deadline day in 2019, it was hoped that the striker could fill the void left by Josh Maja and fire Sunderland to promotion. Sadly, that hasn’t been the case. Photo: Frank Reid
6. KELVIN DAVIES
The stopper joined Sunderland having gained a stellar reputation at Wimbledon and Ipswich. He lasted just one season on Wearside as the Black Cats were relegated from the Premier League - and subsequently joined Southampton. Photo: Stu Forster
7. GEORGE McCARTNEY
McCartney spent two spells with Sunderland - and it’s the second, in which injuries struck - that left fans feeling underwhelmed. His first spell was fairly successful, though. Photo: Jamie McDonald
8. JON STEAD
Once regarded as one of the hottest properties in English football, Stead joined Sunderland in 2005 as his reputation started to grow. He could only muster two goals in two seasons at the Stadium of Light, and was then allowed to join Sheffield United. Photo: Michael Steele
