"I don't sense any apprehension at all," he told reporters. "I just feel we are ready for it and we know what we have to go and do. I am pretty sure everyone will make us the favourites to turn it around.
"In a cup game anything can happen but, with a big pitch and a crowd behind us, hopefully we will be able to score more than we did up in Bradford.
"If we get through, the confidence will be great. The feeling around the club will be massive. It will be a great thing. It can definitely play a huge part in the season turning [around]."
Villa are currently a place and a point above the relegation zone in the Premier League.
