"(Aston) Villa are still in front for Kaboul. They are also about to take Shorey," Redknapp told the Portsmouth News. "I was interested in Shorey so I'm disappointed."
And Redknapp has reiterated he will have to allow players to leave if he is to welcome new arrivals.
"We are going to have to sell one or two to do something," Redknapp added. "It's not a bottomless pit after all.
"You need to sell, really, to bring someone in. That is how it is and how it should be, it's not a problem.
"That's the name of the game. We have to sell one or maybe two to bring someone else in and I accept that."
