Asked if relegation would make him consider his own position at St James’ Park, Ashley told Sky News: “I’ve got no choice.
“I think I am wed to Newcastle like Sports Direct. They’ve got me and I’ve got them. That’s just the way it is.”
Newcastle are without a win in five games but Aleksandar Mitrovic’s late equaliser against Sunderland has at least given them renewed hope.
Benitez will spend the next fortnight ahead of the six-pointer at Norwich trying to find a formula which can bring the Magpies the four wins they need from their remaining eight games.
Papiss Cisse, who has only just returned from injury, came off the bench on Sunday and linked up effectively with Mitrovic.
