Luton manager Mike Newell has revealed he has no written evidence to take to the Football Association this week to support his claims of a bung culture in football.
The former Everton and Blackburn striker will meet FA officials to follow up his allegations that illegal payments are rife in transfer dealings.
'It's word of mouth,' he admitted. 'It's in my head, so I don't know if it's going to be any use at all.
'It will need somebody very strong to support me but nobody can question my integrity. Nobody at the FA can put me on a disrepute charge.
'The problem is, if it's swept aside and there's nobody in the game to investigate.'
Questions are already being asked if Newell has damaged his career prospects by speaking out, but he added: 'I will be very disappointed if I'm hung out to dry on this.
'What might happen to me has never been a concern and I've never given it any consideration.
'If you feel passionate and believe in something, then you have to say it - and I've said it.
'It's something that's bothered me ever since I became a manager. If this causes me a problem in terms of my career, there's something seriously wrong in football.
'I'm not going to back down and be pushed into a corner. It's supporters' money that's going out of the game and that's galling.'
