"I have only got 14 outfield players fit and there is not a spare body anywhere who can play in the Premier League and I am not going to get by on that," the Pompey boss declared.
"I am not close to anybody and cannot say I have got anybody lined up. I am struggling to find anybody.
"It is so difficult to get players on loan, because who is going to loan you anybody?"
Redknapp added: "We need three or four to get us through the month, and I would be happy to get on with that.
"I am definitely short in midfield, because I lose the guys to the African Nations Cup. I have got two forwards, which is not so bad.
"Hopefully we can come up with some names.
"We are looking and I have made some enquires to loan one or two people from clubs like Tottenham, who have got a lot of players, but it is hard. They do not really want to loan you players.
"Suddenly they see us as competition now, a team which may be pushing to get in a UEFA Cup place, the same as them.
"They do not seem to want to help like they used to, when it was, 'oh well, Portsmouth can have them because they are not going anywhere'."
