The R's lost 3-1 to Crystal Palace at Selhurst Park, adding further misery to their already forlorn-looking campaign.
Marsh, however, remained defiant on Twitter, believing his former side most certainly will stay up this term.
All you experts predicting QPR to go down . You're all wrong— Rodney Marsh (@RodneyMarsh10) March 14, 2015
And how QPR will pull off the great escape is by switching to a 4-4-2 formation, according to their former forward.
Marsh has spoken up before about the west London side's need to play a more traditional system - dating back to when Harry Redknapp was at Loftus Road - but the club are yet to heed the call.
I know I said I would never say it again but QPR can only play one system with the players they have!!! 4-4-2— Rodney Marsh (@RodneyMarsh10) March 14, 2015
I'm telling you !! Zamora / Austin up top for rest of season 4-4-2 !!!!— Rodney Marsh (@RodneyMarsh10) March 14, 2015
Judging by Matty Phillips' wonder consolation goal, there is life in QPR yet...
But, judging by the rest of their performance at Crystal Palace, time really is running out for a side completely out of form.
Wilfried Zaha and co made mince meat of QPR as Chris Ramsey's men looked lost in south London. Next up for the R's is a home clash against Everton - before a trip to West Brom.
Crystal Palace, meanwhile, have moved to within two points of Alan Pardew's former side Newcastle United before the Magpies' trip to Everton on Sunday afternoon.
