Trailing 2-0 and outplayed in every position, Redknapp’s QPR again relied on the goalscoring prowess of 25-year-old Austin — who did not disappoint as he moved onto 11 goals to secure a 3-2 win and drag Rangers out of the bottom three.
All 17 of QPR’s points this season have been accrued at Loftus Road but it was the visitors who started well and looked on course to pick up a second successive win as Joleon Lescott and Silvestre Varela took advantage of lax Rangers defending to put the Baggies deservedly ahead.
But Austin pulled one back midway through the first half as he thrashed home a penalty after referee Craig Pawson deemed that James Morrison had pulled back Leroy Fer.
Two more goals followed in the second half for Austin and, although reports last week suggested he had turned down a new deal at the club, Redknapp was adamant there was no chance of the England hopeful being sold in the transfer window.
“If we sold Charlie Austin we might as well go home,” said the Hoops boss.
“He’s here. We need Charlie to keep doing what he’s doing and he can’t afford to take his foot off the gas. His target would be around 20 goals now the way he’s going.”
West Brom boss Alan Irvine again went without his own top goalscorer Saido Berahino in west London, with club-record singing Brown Ideye selected as the lone frontman.
Irvine said: “Ideye is getting sharper and sharper. I feel it’s only a matter of time before he gets his first Premier League goal.”
