Former Sunderland forward Stephen Elliott has slated his old club following five games without a win for Phil Parkinson's side.
The Black Cats are now without a victory since beating Ipswich Town 2-1 at the start of the month.
Since then, Parkinson 's men have been beaten by Mansfield, MK Dons and Fleetwood Town - who they also drew 1-1 with on Friday night - the same scoreline the team recorded against Doncaster Rovers last weekend.
After a strong start to the 2020-21 season, Sunderland still sit in seventh place in the League One table - seven points adrift off Hull City, who occupy top spot.
Elliott played at the Stadium of Light from 2004 until 2007, and scored 22 goals in 81 league games.
The now-retired 36-year-old has criticised his former side for their inability to see out games when in the lead, after Callum Connolly's 73rd minute equaliser following Charlie Wyke 's opener for the away side in Fleetwood.
In Friday night's match, Wyke handed Sunderland the lead with a header just before the hour-mark.
The visitors had a decent penalty shout turned down at Highbury, when Josh Scowen went down in the box following a tough challenge from the eventual goalscorer Connolly.
It was then the on-loan Everton defender who equalised, after finding the bottom right-hand corner, leaving Remi Matthews with little chance in the Black Cats' goal.
Elliott said on Twitter: "5 games without a win at this level for this football club is absolutely abysmal.
Sunderland AFC will be looking to put last season's disappointment behind them and earn promotion back to the Championship in 2019-20, and we'll be following every kick right here on Chronicle Live.
Here are the latest news stories on the Black Cats:
"Only one team trying to win that game in the end and it wasn’t #safc.
"Game management needs looked at. Players on the bench that could make a difference but again we will never know. "
Next up for Sunderland is Burton Albion, who come to the Stadium of Light on Tuesday evening, before hosting Wigan Athletic just four days later, as the side look to climb up the League One table.
