Cambridge United have a work rate admired by boss Michael Duff ahead of this Tuesday's clash at the Jonny-Rocks Stadium.
The U's head to Gloucestershire as one of three sides who like Cheltenham gained automatic promotion to League One via the fourth tier last season.
Duff knows it will be another huge challenge for his players against a team who have picked up some good results in the division so far.
"One thing Cambridge are is they work hard for each other. They're a really good combative unit," he said.
"Ourselves and Cambridge wouldn't have been fancied at the start of last season but the togetherness we had got us promoted.
"We'll have to be a lot more aggressive and combative to get a foothold in the game.
"We've been pleased with how we've done this season. It has been a learning curve and we've had a few punches on the nose along the way which we knew would happen, but hopefully the group are getting more experienced."
