Moyes feels Januzaj has the perfect role model in this respect in Barcelona star Lionel Messi, who has taken knocks throughout his career but, despite his small frame, rides the challenges and is quick to bounce to his feet.
"We've spoken to Adnan about it," added the Reds boss. "He gets kicked in training every day and he gets up.
"He's learnt from the good professionals that he has to get on with it and accept it. He only needs to look at Messi, who is the best in the world at getting kicked and then getting on with it and continuing to produce magic.
"I'm certainly not comparing him in any way to Lionel Messi but the way Messi gets up after getting kicked is how we hope Adnan behaves.
"It's not a case of asking for protection but, somewhere along the line, if he's going to keep playing the way he's playing, then he's going to need to get some protection. We'll never ask for it - it's up to the referees."
