The former Tottenham boss admitted he was light on forward power after long-term injuries to Andy Johnson and Bobby Zamora leaves him with just Djibril Cissé and Junior Hoilett as options.
Redknapp said: “We are not overloaded with strikers here.
“Bobby Zamora's out long-term, Andy Johnson's got an injury – that's two good players to have missing. That's certainly an area we are short in.
“If there's one or two in the window - a couple of loans – then we'd be interested. There won't be wholesale spending."
