Whilst Rovers have been on an excellent winning run and Northampton have been inconsistent throughout this season, boss Tony Mowbray says his side can't be complacent against the Cobblers.
Mowbray's men have won their last six League One games, whilst Hasselbaink's side have won just one of their last five league outings, but the boss knows focus is key for the trip to Sixfields on Saturday.
"We're respectful of every opponent we face. I've told the players that it doesn't matter who the team is, the badge or the shirt they wear, it's just 11 v 11," the manager told iFollow.
"The natural leaders have taken hold. We've seen some intense training sessions and they're determined.
"Northampton beat Walsall in their last game but they've had an up and down time of things. They're looking for back to back wins but we'll be looking to take the game to them."
And Mowbray has once again urged Rovers' travelling support to cheer the team on, with 1,475 tickets all sold for the journey south.
"The fans are hugely important for this team," the boss said.
"The spirit is strong and one thing that will really help is the supporters really getting behind the team and sticking with them.
"I felt it on Saturday against Charlton. The fans rallied when Charlton started getting on top. Having the fans alongside us can help in the momentum and assist us with success."
A reminder that the game at Northampton kicks-off at the earlier time of 2pm.
