Redknapp was coy on his plans for the transfer window, suggesting January often proves a difficult time to bring in quality players.
He said: "Not too many clubs will let good players go in January. It's never an easy time to do business.
"Whoever we bring in here has got to be the right type to get us out of the situation we find ourselves in.
"I've spoken with the chairman about January and the window, but we'll just wait and see what happens."
