Having viewed the replays, Moyes feels Januzaj needs more protection than he is presently receiving.
"I had not seen it until after the game," Moyes said.
"The distance we were from the dug-out made it impossible to take it in.
"It is a bad stamp and it does look deliberate."
Speaking before being made aware of the FA charge, Moyes said of the incident: "That is for the referee to deal with on the day as far as I am concerned. It is over now.
"But I do think Adnan is going to need a little bit of protection or we are going to find that he is getting kicked up and down.
"I do think he deserves a little bit more than he is getting at this present time."
