Paul Dickov says Rovers have no more to fear from Leicester than they have any other club so far this season.
The Foxes visit the Keepmoat with an imposing record of seven wins from their opening nine games, putting them level on points at the top of the table.
Dickov is not concerned with the record of the opposition but appreciates the freedom that not being expected to win brings.
“We know it’s going to be tough for us but no tougher than it was when we played Watford or Wigan, Forest, Blackburn or Burnley the other night,” Dickov said.
“We’ve got to go out there with no pressure and play with no fear.
“Yet again it’s a game where no one is predicting anything from us so that gives us the luxury to go out and have a good go at them.
“After tomorrow it’ll be six of the top nine that we have played already.
“It’s been a tough start for us but it’s been a fantastic start for us because it’s let us know as a club that we’re going in the right direction.”
One thing Dickov does not have the luxury of is a lack of injury worries heading into tomorrow’s clash.
His biggest headache comes from James Husband who is struggling with a shoulder problem.
He said: “We assessed James yesterday and the good thing for us is that there is no dislocation there.
“There’s a lot of swelling and he’s ever so sore.
“We’ll see how he is for Saturday but it’ll be touch and go.
“James being James, he’s got a chance to play.”
Reece Wabara is a potential deputy at left back as he has previously played there.
But Dickov said he may dip into the loan market for cover.
He said: “We’ll have a look today to see how James is and see if we need to bring someone in.
“We’re confident James will be ok, certainly in time for the Reading game.
“So we have to decide if it’s worth bringing someone in for probably just one game.”
Dickov believes strikers Theo Robinson and Federico Macheda will both be fit to play this weekend.
Richie Wellens missed training earlier this week with illness.
