Rovers beat Queens Park Rangers on both occasions last season, but Tony Mowbray has warned that they'll be a different animal on Saturday afternoon.
Mowbray has won five of his eight games against The Hoops as a manager, whilst Rovers have lost only once in the last 22 meetings against the west Londoners.
The performances this term has been solid in the main from Rovers, but they'll be taking on a side who will be looking to bounce back from two successive defeats.
The latest result was a 3-0 reverse at Cardiff City on Wednesday night, but the boss knows just how tough a challenge his side faces at the Kiyan Prince Stadium this weekend.
“They are playing a different system to the one they had last season, they have a new coach and there’s a lot of positivity around their camp at the moment," he admitted to iFollow Rovers.
“They won four on the bounce but have since lost two in a row, so they’ll be looking to bounce back.
“We’ll go there with a positive frame of mind and we’ll look to turn a good performance into points.
“West Brom, in their last home game, they were undone by a free kick that went under the wall and a left back who produced a solo run before scoring.
“It’s a nice environment to go and play. I’ve had some good experiences of QPR away, so let’s hope there’s another one this weekend."
Rangers' formation is something of a throwback to yesteryear, with Mark Warburton opting for two strikers up front in experienced suo Jordan Hugill and Nakhi Wells.
The pair have five goals each already this term and Mowbray added that they will have to be watched.
“Jordan Hugill’s powerful, they play three at the back, two wing backs and Nakhi Wells up front as well," he said.
"They know where the goal is, Hugill and Wells. I watched Hugill a few times at Middlesbrough last season and Wells has scored quite a few goals in recent weeks.
“He knows how to sneak into areas to score goals.
“But we’ll go there in confident mood. We feel we’re better than the one point from the last two games, but at some stage we need to prove that by getting more points on the board.”
