Wales and British and Irish Lions fly-half great Phil Bennett is concerned that Warren Gatland's current side are playing too many Tests in November.
For several years now Wales have played an "extra" fourth Test outside the World Rugby international window.
This season only Wales and England out of the northern hemisphere sides are playing four Tests in the autumn.
"Sometimes I think it's asking so much of the players," said former Llanelli stand-off Bennett, 66.
South Africa are Wales' final opponents on Saturday, a team they have beaten just once in 1999.
"I looked at the expression of the boys at the final whistle [against the All Blacks]; they were out on their feet, they were physically gone, they were mentally gone," Bennett said.
"When you think these players have beaten themselves up for three weeks, then there's a fourth game coming up on Saturday.
"Then they go back to their regions or clubs... and they're involved in two huge European Cup matches."
