Michael Vaughan believes the England selectors must rest skipper Andrew Strauss for next year's tour of Bangladesh.
Strauss has indicated that he may opt to sit out the month-long two Test and three one-day international series, which begins in late February.
The England and Wales Cricket board are due to make a decision on which players will be rested after this winter's tour to South Africa, however, Vaughan believes a decision should be made now.
The former England captain is wary of a hectic summer schedule, which precedes England's quest to retain the Ashes in Australia at the end of the year.
"This needs to be addressed now. Andrew Strauss should be rested for that trip, as should Paul Collingwood, as should Jimmy Anderson," Vaughan told The Guardian.
"They should announce it now because until they do, if the South Africa series goes wrong, then I guarantee that Strauss, Anderson, Collingwood will end up going to Bangladesh.
"I know what will happen. I've been in the job and I know what happens with the England selectors and I know what happens with the England team.
"We might lose in South Africa, we might lose heavily. Then everyone will start to worry about their position in the team, about young guys coming in.
"They will know that whoever you put in the team for Bangladesh should do well, so the players will start to get a little bit frightened about their position in the side.
"The selectors will say, 'We must start winning again' ahead of the next Ashes.
"England have got to let the players know they're being rested now so that if the South Africa series doesn't go the way we want it to there is not a mass call for these guys to go Bangladesh."
Vaughan also admitted the rigours of being England captain, and staying away from his family for extended periods, had contributed to his decision to stand down from the post in August last year.
The Yorkshireman believes Strauss would benefit long-term from being given time away from the game to be with his family.
"For five-and-a-half years I'd devoted every single moment of my life to being the England captain," he added.
"I'd lived and slept in the job. It takes a toll. And at the end I just knew I had to get my life back."
