Dennis Wise admits his management career is in tatters over his controversial spell at Newcastle United.
Ex-Chelsea and England midfielder Wise was sacked in April but believes Kevin Keegan is the only man who should have his behaviour scrutinised.
Wise insisted: "It has all had a damaging effect on my career and has not been fantastic for me. But you have to make decisions and live and die by them. It's sad because I was going into that job trying to do my best for the club. I left a good job at Leeds to go there and thought I was going to better myself.
"At the end of the day, Mike (Ashley) sacked me. There's been a lot of speculation about the situation with agents. I have to be careful what I say but the club never paid money to an agent. We brought a loan player in but there was no loan fee or agent fee.
"The long-term idea was we would have first option on all the best young South American kids and that was important to the club.
"Mike knew all about it and was fine. He knew about every deal. He's the owner and it's his money. The disappointing thing is that if Kevin had won £25m that would have upset Newcastle United Football Club.
"Mike was worried about it. When someone is suing for £25m, you have to panic a bit.
"It's not a nice situation to be in. Maybe that would have ended in administration. Maybe, that's a question for Mike."
