Former Wales captain and Shrewsbury manager Kevin Ratcliffe has revealed he was offered a bribe to sign a player.
Ratcliffe said the illegal practice was widespread throughout the Football League, backing Mike Newell's claims which have rocked the sport this week.
"I never received anything but I was offered something if a transfer would happen," Ratcliffe told BBC Sport.
"But believe me, it wasn't worth risking your career over and the deal didn't go through in the end anyway."
Newell, a former Everton team-mate and close friend of Ratcliffe, says he will give the Football Association the name of agents who have offered him bribes over potential transfer deals.
Ratcliffe praised Newell for speaking out, but fears his honesty could jeopardise his future career prospects as a manager.
He also doubts whether any potential FA investigation will uncover any concrete evidence of so-called bungs.
"I'm surprised any manager has come out with this, but with the transfer window open I think he [Newell] has come across some obstacles," said Ratcliffe, who started his managerial career at Chester in 1995 before moving to Shrewsbury four years later.
"He's most probably been frustrated he can't get hold of players that he wants because certain people want back-handers.
"I think it happens throughout the leagues, but obviously everyone's looking at the top end and wandering what's happening."
Cardiff City manager Dave Jones and Swansea City manager Kenny Jackett say they have never received or been offered bribes.
Wrexham manager Denis Smith says he has been offered a bung only once in over 20 years as a manager.
"It was when I was at Sunderland and it was from a foreign agent," Smith told BBC Wales Sport.
"I turned it down and the deal fell through. It's not as rife as some people would like to think, but I'm sure it happens. The problem is proving it."
And Ratcliffe, who has been out of football management since quitting at Shrewsbury in 2003, says there is no reason to doubt Newell's claims.
"He's a likeable lad and he's got a good work ethic," said Ratcliffe.
"He does shoot from the hip sometimes, but there's no reason his allegations aren't true.
"It could put his career on hold because the agents work for the chairmen of football clubs as well.
"He's very brave for doing what he's doing and I hope somebody gives him the big chance he deserves one day.
"You need strong evidence to prove his allegations and I'm sure chairmen, managers and agents are going to stick together on this one."
