Donal Óg Cusack said Waterford's "atrocious" form is a serious concern for the county and a "major review" is required to address internal issues.
The Déise were hammered by Limerick 2-24 to 0-10 at Walsh Park on Sunday, their third loss of the Munster Championship. Manager Paraic Fanning said afterwards that his side face "a lot of soul-searching" but Sunday Game analyst Cusack went further.
"Their form has been atrocious," he said. "Since the 2017 All-Ireland final they have been on a losing streak. It's going to be extremely hard to pick it up. I think there's a major review need in the Waterford set-up and as a total, not just on the field.
"They've some fantastic players. A good friend of mine has been involved with UCC for the last number of years and he's been continuously been telling me that the best young players there are from Waterford.
"I think someone needs to go. I know from a player's point of view, when you believe so much in a management, and if you think that the new management that's come in aren't going to advance you... it's like if you did a degree and you wanted to push on and do a Masters pr a PhD that you're possibly being brought back to secondary school.
"That can happen and that perception can exist. When that happens there's big trouble in the camp."
Henry Shefflin agreed with the Corkman's assertions, and questioned the commitment levels of some of the players.
"We thought there would have been soul searching the last two weeks," he said.
"We thought today they were going to come with something different. It was worse.
"We grew up in a time where Waterford had such (good) Players: Mullane, Ken McGrath, Dan Shanahan and most of all Tony Browne. They died in their boots for Waterford. They played with their heart, they played with passion. We're not seeing that with some of the players now.
"Derek McGrath was so systematic in the way he managed the game and his man-management of it.
"Paraic is not as systematic and doesn't have the same man-management skills. There seems to have been a derailment since Derek has gone."
