Newcastle United are currently six points adrift of safety.
Newcastle are now battling against the odds to survive, and Collymore feels that they will ultimately come up short as they aim to stave off relegation.
“Newcastle are as good as down,” Collymore said. “They’ll go. I look at them and I think it’s that the archaeological dig of several managers has hurt them.
“That means that one manager from five years ago buys this group of players and some of them are still there, the next manager comes and and buys another group of players and so on and so on.
“That means that instead of getting a natural and cohesive philosophy like Leicester, you get lots of different players who have different styles now having to listen to Benitez and stay safe.”
Newcastle placed Rafael Benitez in charge for the last 10 games of the season in a last attempt to save themselves from the drop.
The Spaniard has sparked an improvement in Newcastle’s performances, but he is still waiting to celebrate victory.
