The Blades sat seventh in the top-flight standings and within touching distance of a Champions League place when 2019/20 was suspended due to the coronavirus outbreak.
Here's a look at the players who are in contention for selection by Chris Wilder at Villa Park.
The Blades' number one is on-loan from Manchester United.
George Baldock has played every minute of all 28 of United's Premier League matches.
Enda Stevens has been another ever-present, on the left-hand side of Chris Wilder's defence.
John Fleck has netted five times from the centre of midfield.
