Wycombe midfielder Matty Bloomfield has warned his team-mates they will face "a massive test" against Rotherham.
Gary Waddock's side won 4-3 at the Don Valley earlier this season and Bloomfield - who scored in that success - expects the Millers to come out fighting this weekend.
He said: "They will be a wounded animal and will want revenge for the defeat up at their place. The gaffer will prepare us right and we will go again.
"They are a team that want to go for promotion and they got very close last season but didn't quite make it.
"They want to go one better this season and they are a very strong side and it is going to be a massive test for us.
"We are at home and we will approach it in an attacking way and try to get the win."
