Backed by owner Tony Fernandes, Redknapp has brought in Alex McCarthy, Rio Ferdinand, Steven Caulker, Mauricio Isla, Leroy Fer, Jordan Mutch and Sandro, whilst Niko Kranjcar extended his loan from Dynamo Kiev and left back Jack Robinson was signed from Liverpool before being loaned out to Huddersfield for the season.
With only Loic Remy, Charlie Austin and Bobby Zamora at his disposal as the season started, it was imperative that Redknapp added another striker, and despite reported interest from Arsenal and Sunderland, Rangers managed to snap up Napoli forward Eduardo Vargas on a season-long loan deal.
The 24-year-old Chilean international made his name with Universidad de Chile with 29 goals in 50 games, but his time at Napoli wasn't quite as successful, as he only hit three goals in 28 games. Loan spells to Gremio and Valencia followed, yet the goals appeared to dry up again with only 14 in 62 over those two stints.
Now he comes to the Premier League in a bid to rekindle his goalscoring touch, and his first game could be against Manchester United after he was handed a work permit to play in England.
As he looks to make an impact in English football, a debut against United could be the best thing for him. Louis van Gaal's side have looked poor so far this season, particularly in defence as the players look confused at how to play in the Dutchman's 3-5-2 system.
With his blistering pace, Vargas could cause some problems against United - and QPR will need him to do that throughout the season if they are to stay up.
