However, the 44-year-old has suggested that Dick Advocaat’s appointment as the Black Cats boss may not necessarily be the key factor.
“Advocaat has a decent reputation, especially on the continent, but then so did Felix Magath at Fulham—and look what happened there,” Collymore wrote in the Bleacher Report.
“Does he know any of the players? If he’s asking his assistants for information on players and their strengths and their weaknesses in training, then how is he going to make a real impact in eight weeks?
“How is he going to know which players to give a kick, and which to give a cuddle? These are important details.
“Sunderland might still have enough to stay up—their defence is generally okay, and that might save them—but that could end up being as much to do with the weakness of other teams as Advocaat’s impact.”
Advocaat was appointed the Sunderland boss earlier this week following the dismissal of Gus Poyet.
The Dutchman has been given a contract which runs until the end of the season, and he has to hit the ground running.
Sunderland are currently a point clear of the Premier League relegation zone and do have a squad which can avoid the drop at the end of the season.
As Collymore suggests, Advocaat will need some time to get to know his players and will need the first-team coaches to help him out initially.
However, the 67-year-old should be trusted to make his own decisions and must be given the benefit of the doubt in the initial weeks.
