Pardew, whose side travel to Old Trafford today, said: "The Van Persie one is not as bad as Alex thought.
"It can look worse from the sidelines - I'm not sure any action will be taken.
"But certainly with regards to elbows and off-the-ball incidents, it's good that the FA have brought in retrospective action.
"I don't think it's significant that United dropped points on Sunday.
"That's slightly insulting to Alex - he felt that at the time and you need to protect your players."
