However, the arrivals of Alex McCarthy, Mauricio Isla, Steven Caulker, Rio Ferdinand, Sandro, Jordon Mutch, Leroy Fer and Eduardo Vargas haven't helped so far.
Rangers have won just twice this season, and Redknapp's men are struggling, just one spot above bottom club Burnley - piling the pressure on the manager.
If there is to be one one bright spot from a difficult season so far, it's Charlie Austin. The former Burnley and Swindon Town striker has hit five goals in nine games so far this season, accounting for over half of the club's goals this season.
The 25-year-old smashed 20 goals in 37 games last season to fire the club to promotion, and it's clear that his predatory instincts are still intact in the Premier League.
Saturday's instinctive flick against Chelsea gave QPR a fighting chance against their West London rivals, and manager Redknapp says that his star striker could yet become an England international.
"Charlie's improving and if he keeps scoring goals there no reason why he can't in the future," said Redknapp.
"He's a great lad, good attitude, not a minute's problem and he enjoys being a footballer. He's had it the hard way and I think he realises just how fortunate he is to be doing what he does."
"If he keeps scoring goals and improving his game there’s no reason he can't make the breakthrough," he added.
The likes of Stewart Downing and Saido Berahino have been rewarded with England call-ups for their great form so far this season, and if Austin continues to find the net, he should be on Roy Hodgson's radar.
