All of these players could soon walk away as free agents, but who is in-line for a new deal with Sunderland?We take a look at all the players facing an uncertain future, and whether they are likely to be turning out for the Black Cats again next term:
5. Kyle Lafferty
Lafferty began to show glimpses of his undoubted quality before the season was suspended, but his long-term future remains unclear. Whether Sunderland could sanction the spend to keep the striker - and indeed whether Lafferty himself would fancy another season in League One - remains unclear. Photo: FRANK REID 2019
6. Tom Flanagan
Phil Parkinson has praised the versatility of the centre back and, given the current footballing climate, it would be a sensible piece of business to keep the Northern Irish international. Photo: COPYRIGHT (C) FRANK REID 20187
7. Duncan Watmore
While he could undoubtedly be a key player in any potential promotion push next season, the fact Watmore is the last remaining player on a contract issued during the club's Premier League days mean his future is uncertain. Photo: FRANK REID 2019
8. Ethan Robson
Still yet to be given a real opportunity at Sunderland, Robson is at a point in his career where regular first-team games are a must. If there are no such promises made on Wearside, then a summer exit looks likely. Photo: FRANK REID
