Plymouth Chief Exec Keith Todd claimed Ridsdale was on holiday in the South West when watching the Plymouth home game but then he turned up against at Plymouth's next match much to Todd's surprise.
"Unbelievable, isn't it," Todd laughed with the Guardian, when asked about Ridsdale's latest appearance. "He was not an invitee of ours. He was invited by Oldham and we happened to be there. I am not expecting it to happen at future matches."
And Ridsdale? "I'm a football person, I've been in the game 25 years," he said. "The base I left at Cardiff is proving I can do a decent job. I'd love to be back involved in football."
