Don Hutchison has has slated Sunderland's squad on Channel 5, after they were dumped out of the Capital One Cup on Tuesday night.
Sunderland lost 4-1 to Manchester City in the third round of the competition, and their performance was well short of the standard required.
It exposed the problems that the Black Cats have suffered with all season, and Hutchison says that there are simply too many average players in the squad for things to improve.
"Dick Advocaat has been left with a very average squad, where a lot of players need moving on," he said. "They can't do that for a long time, until the window opens.
"I feel sorry for Advocaat. I don't think he knows his best back four. I understand Billy Jones plays at right-back and Patrick van Aanholt at left-back, but he's got four centre-halves - John O'Shea, Wes Brown, Younes Kaboul and Sebastian Coates. They're all above average players, but there's not a lot else.
"Going forward, there's not a lot of legs in the team. He's got Fabio Borini in, who he spent £7 million on, and him and Jermain Defoe could forge a partnership, but he won't play him. He plays one up-top, and the other has to play on the left or the right. It looks as if they are going down."
Sunderland are still looking for their first Premier League win of the season and they currently prop up the table, as a result.
The Wearsiders have been well off the pace, with their defence looking weak and their attack appearing toothless.
It leaves them already embroiled in a relegation fight once again, and a long season seems to be on the cards at the Stadium of Light.
Sunderland's next match is against Manchester United, before they face games against West Ham United and West Bromwich Albion, where they will simply have to get a result.
