"It's going to be a difficult call for us to win it but you approach every tournament with a belief you can win it and not to make up the numbers," he said after the 3-1 win at Molineux.
"No-one could fault us today because we played really well and thoroughly deserved our place in the next round.
"People keep talking about 1980 and all that but I wouldn't say it was a millstone around my neck or anything like that.
"But there's a tradition about us and hopefully the fifth-round draw will be kind to us and get us a home tie.
"There's a buzz about the place at the moment, training's double lively and all the players who went out there today were determined to do well."
