Portsmouth chief executive Peter Storrie has dismissed speculation suggesting the club have joined the race to sign striker Mauro Zarate.
The Argentinian forward has returned from a loan spell at Birmingham to United Arab Emirates club Al Sadd and is believed to be available for around £10million.
"That's absolute nonsense. I don't know where that story has come from but he is not one of the players we are looking at," Storrie told the Portsmouth News.
Liverpool striker Peter Crouch remains a target and Portsmouth have maintained their interest despite Rafael Benitez slapping a £15million price tag on the player.
Crouch has twice played under Redknapp at Portsmouth and Southampton, with the manager making substantial profit for those clubs by selling him to Aston Villa and then Liverpool.
Redknapp remains an admirer but would have to depend on Liverpool lowering the fee or offering Pompey players - possibly Croatian winger Niko Kranjcar - in exchange.
