Rangers have been linked with a loan move for the 22-year-old, who is also on the radar of Parma.
Redknapp is keen to add another forward to his team as Bobby Zamora and Andy Johnson have both struggled with injuries, leaving Charlie Austin to score the goals this season.
Chairman Tony Fernandez and chief executive Phil Beard have been trying to tie up deals before the end of the current transfer window.
Redknapp said: "I'm not sure to be honest exactly where we are at with it. Phil's dealt with it, and the chairman or whoever, and so I wouldn't be sure at the moment.
"He's a player we would be interested in but I couldn't sit here and say how close it is really.
"I've not got involved in dealing with the clubs or anyone else so I'm not sure what the problems are.
"He's a front man and we've been looking for another forward. We've got Charlie and Andy J is getting fitter, which is good. And Bobby Zamora, so he'll give us another good option.
Redknapp has ruled out linking up with Stoke strike Peter Crouch, though, having worked with the giant forward at Tottenham, Southampton and twice at Portsmouth.
"I think that's unrealistic. He's in the team at Stoke and we haven't made any enquiries about Peter at all," Redknapp added.
"If we can get a striker in that would be good. That's an area we are looking at, and also looking to maybe bring another defender or something."
Meanwhile, Sky sources understand Livingston defender Coll Donaldson will sign for QPR on Tuesday on a three-and-a-half-year deal for a fee of around £150,000.
