The Hoops manager admits he will find it hard to offload some of his flops - but equally difficult to keep hold of stars, such as striker Loic Remy.
Redknapp said: "I wouldn't be looking to spend a sizable amount.
"You don't have to spend fortunes. The players are out there. There are enough good players here to give you a platform to work with. We just need a few characters.
"The silly thing about this game is the ones you want to keep are the ones who want to go, and the ones that you would like to let go don't want to go
"Remy's done great. He could score 20 goals a season in the Premier League.
"He's our leading scorer and he's only played a handful of games. We'd like to keep him but we'll have to sit down and see what his plans are."
