Clough added: "We put everything into Tuesday's match.
"It's a big stage and as well as physically it takes it out of you emotionally to play in front of 70,000 people."
The former Burton manager admitted he did have a few injury worries ahead of Friday night's clash.
"Andy Todd strained a hamstring at Manchester United, so he'll be struggling for Friday evening as will Steve Davies who's got a very slight groin strain," said Clough.
"Kris Commons had two or three stitches in a small gash on his shin but should be ok if needed and selected."
