The pair failed to get off the bench in victory at Wolves.
Pardew told the Evening Chronicle: "It's not a headache, but a nice problem. I didn't use Ben Arfa because I thought with the pace of the game, and the way we were defending, we weren't going to get enough ball to him.
"Peter (Lonvenkrands) came on and did a sterling job.
"There'll be other games for Ben Arfa to come on, for sure, and Santon."
