Spurs has been linked with a move for the duo in recent months.
“I liked Scott when he played for Hibs, while he has gone on and done great things at Celtic,” Redknapp is quoted as saying in The Scottish Sun.
“Aiden, obviously, is a real talent. But I’m not trying to buy either of them, and I did not try to buy McGeady or Brown in January. Celtic don’t want to sell them anyway, do they?”
