The Reds tasted glory at Wembley last season, when overcoming Manchester City in a memorable final, and safely negotiated a very difficult third-round challenge posed by Arsenal at the Emirates Stadium last month.
Altay Bayindir was the hero as we knocked the Gunners out on penalties on their home turf.
Our reward is the home tie against Ruud van Nistelrooy's Leicester City, with the game kicking off at 20:00 GMT.
The victors, to be decided on the night with replays no longer taking place, will then sit pretty, waiting to see who else gets through all the way up until Tuesday night, when Exeter City meet Nottingham Forest in the final fourth-round match.
