The Scottish champions fought back from behind for the sixth time this season to claim all three points in the Clydesdale Bank Premier League, with Miller netting a hat-trick in the 3-2 win on Saturday.
The striker said: "Of course this win sets us up nicely.
"We will have to soak up a lot of pressure and we will have to win the game if we are to have a chance of qualification so we are going to have to create a few chances.
"We were disappointed with how we played on Saturday but we've got to be positive going into the game on Wednesday night."
Wayne Rooney is set to be unleashed in Glasgow after returning from injury as a substitute in Saturday's 2-0 win against Wigan.
Miller added: "He is a fantastic player but he is one of many they've got.
"It's not Wayne Rooney we will have to worry about, it will be the whole team, whether it be Berbatov, Nani, Scholes or Giggs.
"It's going to be a tough night for us and we are going to have to ride our luck and play well and hopefully take the chances when they come along."
