Pardew told talkSPORT: "You've got your skipper out there, you've got a technical skipper, when you've got a technician as a skipper, I think it's always dangerous because they're going to have off games. Even [Christian] Eriksen in his prime, [Michel] Platini in his prime, they'd have the off day. They were technical players."
He added: "[Against Liverpool], it was never Fernandes because [United] never had the ball enough. Defensively, he's not been called upon. How can he lead the team? It's a very difficult one for him.
"I actually think it would be better for him as a footballer to take it off him. I think it might free him up a bit, let him be a bit more free-minded. He's probably worrying about the back four, worrying about the wingers. You don't really know how to deal with it.
"I don't know, I think it's a hamper to him."
