The 23-year-old joined the Championship side shortly after Austin departed for Southampton.
Queens Park Rangers captain Nedum Onuoha is hoping that the club's new signing Conor Washington will be able to just concentrate on scoring goals, rather than trying to replace Charlie Austin, Get West London reports.
Shortly after Austin left Loftus Road for Premier League side Southampton, the Hoops signed the 23-year-old from Peterborough for £2m (via Get West London). And while Washington's arrival would appear to have stemmed from the 26-year-old's departure, Onuoha suggested that his new teammate should not concern himself with trying to live up to any potential comparisons between the two forwards.
"The job of the number nine is to score goals, and whether it's Charlie Austin, Jamie Mackie, Conor Washington or Sebastian Polter - that's what they have to do," he told Get West London.
"It's not so much about trying to fill Charlie's shoes, it's trying to fill the expectation of what you should do."
While Washington has yet to score for Jimmy Floyd Hasselbaink's side in either of his two appearances, he has already proved this season that he should be more than capable of firing Rangers up the Championship table.
For the Posh, he bounced back from a very slow start to the campaign - where he managed just one goal in his first 12 games in all competitions - to put together the kind of run that gave his new club the confidence to go after him.
His 14 strikes in his last 19 appearances before his move - which included 10 goals in the league - helped propel him right up the League One goalscoring charts, and Onuoha will be hoping that his new teammate can enjoy a similar spell of form over the coming months for his new side.
