The Magpies head coach has been discussing his side's dire predicament.
Indeed, McClaren says he used to speak to Redknapp, who told him that he would have a 'massive party' whenever he reached the magic 40-point mark that usually guaranteed survival.
And the Newcastle head coach admits that has now become his main goal.
The Newcastle boss is quoted as telling reporters: "I remember having conversations with Harry and he used to have a massive party whenever he got to 40 points.
"Whether that was in November, March, April, whenever - he’d say ‘right, we’re having a party now’. It’s all about getting to that 40-point mark, then you can think about other things."
More strangely timed comments from McClaren?
You often wonder if the Newcastle boss is deliberately trying to get himself the sack with his comments.
On this occasion, he's also contradicted himself. Recently, McClaren spoke of starting afresh and acting as though it's a new season against Norwich City.
Now, the Magpies boss is essentially writing the season off?
If the Newcastle head coach is confident of turning things around, he wouldn't need to mention the 40-point mark. There are still 90 points to play for...
Obviously, though, McClaren is starting to recognise his own shortcomings.
If McClaren is using Redknapp as his role model when it comes to fighting relegation, meanwhile, maybe that's another bit of evidence for why Newcastle are... in the relegation zone.
