Boss Gary Bowyer isn't surprised to see Brentford doing so well this season.
Despite being one the Championship's new-boys at the start of the season, Mark Warburton's side have had an impressive campaign to date, and currently sit fifth in the table.
Rovers could go about the Bees with victory at Griffin Park on Saturday, but with a home record of six wins, three draws and just the one defeat, Bowyer knows it won't be easy.
"I think they've done magnificently well," said the Rovers boss. "They've come up and some people would say that they've surprised the league, but we've watched them on numerous occasions and they haven't surprised us.
"They've got some good footballers, they've got good technicians, they've got pace up front and they are well managed and well coached.
"We know it is going to be a difficult game because of the environment down there. It is one of the old-fashioned grounds where the crowd is right on top of you, so it is something that we are looking forward to."
One player who the Rovers boss needs little introduction to is former Academy product Alan Judge.
The Irishman was one of Bowyer's first signings when he became Rovers boss, but due to a lack of first team possibilities, he reluctantly allowed Judge to move on.
"As soon as we got the job we wanted Judger back because we knew of his passion for the club," added Bowyer.
"But he found himself out of the team and desperate to play. That is a credit to him, he didn't want to just be a bit-part player or a squad player until he got his opportunity, he wanted to be playing football.
"He went away and got Brentford promoted, we know what he is all about and I'm sure that he is really looking forward to the game."
