Sunderland manager David Moyes has called for agent fees to be published to show the truth behind player transfers.
Sam Allardyce, who preceded Moyes at the Stadium of Light, left his job as England boss on Tuesday following The Telegraph's investigation into alleged corruption in English football.
Speaking to Sky Sports News, the former Everton and Manchester United boss said: "In my time, I've not seen much or any of it, probably. I think it would be great if everything was more transparent in general. If you're a fan and your club signs a player you don't get to know what the agent's fee is on the deal.
"If we published those then we might get a few shocks. Then maybe people could see that signing the player isn't the only cost. The football clubs would have to show how much they're giving individuals.
"[It wouldn't be a very good thing for the agents] but it doesn't look like a very good thing for the managers or the coaches at the moment by some accounts. It's only my opinion. I think if we did that there would be a few more gasps."
Moyes is yet to win a Premier League game as Sunderland manager since taking over at the Wearside club following Allardyce's departure.
