Darren Moore believes Rovers will have to be at their best to earn a result against Lincoln City this weekend.
The Imps are currently top of Sky Bet League One, and Moore has been impressed with their start to the campaign.
He said: “It’s a team that’s been put together well over the past year and they have the right players in the right areas.
“They possess a huge threat and they’re a team who consistently look to get on the front foot and cause you problems.
“I know the manager very well and he’s put a team together that fit the way he wants to play football.”
Rovers are currently three points off the places with eight games played, and Moore expects it to take a few more weeks for the table to truly take shape.
He added: “It’s normally not until 12 games in that you look at the table but this season it’s come around quicker with the fixture list being so compact.
“We’ve got a midweek game most weeks now so the table might still change once teams get used to the demands of the league.
“We’ve had our fair share of injuries early doors so we feel that while we’re happy enough with the start, it could have been much better.”
