Toon boss Alan Pardew recently revealed that a deal was now in place, but conceded that the situation was 'complicated'.
The Evening Chronicle reports, Redknapp saying: "I don't know what the deal is. I don't know what the chairman Tony Fernandes or (chief executive) Philip Beard have agreed.
"I don't know whether there's a fee agreed or not.
"He's certainly playing well for them. I said last season that he's a 10 to 15-goal a season man."
