"If we can get one or two in, we'll give ourselves a chance. That's what I'm looking at," said Redknapp, who denied having made an approach for Hangeland.
"If I can't bring in people who I think can do the job for us, then I won't bother. There's no point signing players for the sake of it.
"I've got to sign people in the right positions who can help us. If we can't do that, we may as well sit tight and see what happens."
"We'll have to look at that and see how we're going in January," added Redknapp.
"I can't look to get rid of anyone - I had to pull in a kid who had been on loan at Yeovil on the bench against West Brom.
"We're certainly not over-loaded. Out of the 25 we have long-term injuries. I won't shift people out unless I get some in."
