Michael Doyle insists the Blades will be firm underdogs in Sunday's FA Cup third round tie at Loftus Road, despite their recent exploits in cup competitions.
The Blades skipper says United will face a 'team packed full of Premiership players' regardless of what team R's boss Harry Redknapp opts to field following Thursday's draw with Swansea City.
Looking ahead, Doyle remerked: "People perhaps look at Sheffield United going to QPR, whose priority is obviously top flight survival this season, and expect an upset, but they will start as big favourites.
"They have got a big squad and whoever we line up against, the fact is they will have a team packed full of Premiership players, who will be probably looking to prove a point to their manager.
"But all our cup successes in the last year or so have been deserved victories, we haven't been lucky or fluked any wins, so we will go to Loftus Road with a gameplan and hopefully it will be another day to to remember for the fans."
The midfielder added: "The FA Cup is a special competition, it always will be and hopefully it can have a similar impact on our league form this season as it did last.
"We aren't daft enough to look beyond QPR though and at this stage we haven't even thought about what we achieved last season.
"That is in the past now, it is a memory that we won't forget in a hurry, but emulating that isn't our focus at the moment.
"A positive result against QPR will hopefully give our league form a boost ahead of what is a crucial month ahead."
