The Blades have enjoyed their FA Cup run thus far, beating fellow Championship opposition Ipswich Town and Preston North End (both 1-0) in the last two rounds. Billy Sharp netted from the penalty spot as the Blades earned a victory over Preston yesterday.
Written prior to todays fixtures between Chelsea and Newcastle United, and Cardiff City and Manchester City - there are some intesting replays to note. League Two side Newport County were unfortunate to draw 1-1 with Tottenham Hotspur but will no doubt be looking forward to a replay at Wembley Stadium. Meanwhile Huddersfield and Birmingham, Notts County and Swansea and Millwall and Rochdale will all have to do it again in ten days time.
Potentially the Blades could draw rivals Sheffield Wednesday who beat Reading 3-1 at Hillsborough on Friday night. The Owls have been allocated ball number #6.
The draw for the Fifth Round will take place tomorrow evening at around 7:20pm and can be watched on BBC One's The One Show.
