Pearce has been handed the temporary role following Fabio Capello’s resignation earlier this month, and the former Manchester City manager will take charge of England’s friendly against the Netherlands next Wednesday.
“I think that’s a decision the FA need to make for the right and proper reasons,” said Pearce on Thursday.
“I’ll support whoever comes in. Whatever level that will be, fine. If he doesn’t want me in his set-up, I’ll support him from afar as Under-21s manager.
“That’s part of leadership – giving yourself for the greater good. By appointing me on a short-term basis, they’ve got breathing space, which is right and proper.”
Pearce named uncapped duo Fraizer Campbell and Tom Cleverley in his squad for Wednesday’s friendly, while Micah Richards and Steven Gerrard also return to the national set-up.
But Pearce refused to disclose who he will select to captain England against the Dutch at Wembley.
“I think the exposure for the captaincy issue over the last few months has been excessive,” he added.
“But I’ll pick a man. I’ve got my own ideas on who’s respected. That’ll be decided nearer the time.
“I’m managing on a one-off basis so to look at a long-term situation is difficult. At this moment in my development, the job as manager is not for me.”
