And McArthur is aware some Newcastle fans may want to voice their criticism of the coach from the stands - as they had done throughout his tenure at St James' Park.
But the 27-year-old has warned those supporters that their noise will be drowned out by an exceptional home support from the Crystal Palace faithful.
"The atmosphere will be something extra special," the midfielder told the Mail. "I know their fans will give him a bit of abuse but our fans are right behind him and they’ll make sure to drown out their fans.
"Selhurst Park is a a nightmare place to play away. We played here in the Cup when I was at Wigan and lost and it wasn’t nice. It’s a true fortress, the fans are loud, rowdy and it makes it hard for any team to come here and get a win."
McArthur himself was involved in a strange altercation with Leicester City boss Nigel Pearson at the weekend during Crystal Palace's win over the Foxes.
Since, both he and Pearson have appeared to play the incident down, although - whether jovial or not - Pearson clearly had his hands around the Palace midfielder's neck.
With regards to tonight, though, Crystal Palace - Newcastle promises to be a tasty encounter. If not from the footballing perspective, at the very least in terms of atmosphere.
