Manager Garry Monk says Swansea have analysed QPR striker Charlie Austin ahead of the Premier League match at the Liberty Stadium.
Striker Austin has scored five times in five games, including the winner in the 3-2 win over Leicester on Saturday.
Monk says QPR will have momentum after that win lifted them off the bottom of the Premier League table.
"Coming off the back of a good win gives you confidence and a belief and it's going to be difficult," he said.
"You analyse all their players but him [Austin] especially, he's in very good form at the moment and he's a good goal scorer.
"But they have other good players as well and other threats from around the pitch, so it's a tough game for us again.
"I said before the Palace game it will be extremely hard and difficult and QPR will be no different."
Monk's team go into the match off the back of a disappointing 1-1 draw with Crystal Palace at the Liberty Stadium.
Eighth-placed Swansea are eight points and 10 places ahead of their opponents in a match that pitches Monk, at 35 the youngest manager in the Premier League, against Harry Redknapp, the oldest at 67.
And Monk, who took over from Michael Laudrup as Swansea manager on 4 February 2014, says Redknapp's career is a fine example for any young manager.
"If you look at the longevity he's had at this level - if I could have half that career I'd be doing something right," added Monk.
"He's a good guy who knows his football and what he's done in his career he's created good squads who play good football. A career like his, it's something I aspire too as well."
QPR arrive at the Liberty Stadium having lost all of their away games since returning to the Premier League this season.
But that statistic offers no comfort to Monk.
"They want to put points on the board away from home as soon as possible and I think they will have targeted this game as one where they can do that," he added.
