Celtic goalkeeper Craig Gordon has said that he should have taken a cut of the transfer fee when he moved from Hearts to Sunderland.
The Scotland international moved to Sunderland in 2007 for a fee of £9m and waived a bonus that he was due to be paid by Hearts.
"When I left Hearts I didn't take anything with me from the transfer fee or any signing-on fees. I left that with the club and it's probably long gone," Gordon told the Daily Record.
"Maybe it would have been better had I taken it with me so I could put it back in now. I waived what I could have taken because I thought that was the right thing to do.
"I'm annoyed to think that the youth academy maybe didn't get that money. "Maybe it did go towards youth development, maybe it didn't. I've no idea. But it would have been nice if a certain percentage of that had managed to filter through."
Gordon made 88 appearances for the Black Cats before moving to Celtic in 2014.
