The Latics entertain Notts County at the DW.
"You approach the FA Cup knowing that it is a one-off situation," he said. "You need to be as good as you can be and there is no margin for error.
"All the credit needs to go to Notts County, but the way we reacted in the second half and the way we got back into the game showed a lot of good things on our part.
"We are looking forward to the replay, it's going to be an exciting game.
"It's a unique opportunity for both football clubs to get into the fifth round and it's going to be a typical FA Cup encounter."
