As per last season, United's first team will spend time in Portugal at the beginning of July, and the Blades have a fixture against Real Betis at the Algarve Stadium on Friday 12th July (KO 8pm local time).
Upon returning home, United will play four away friendlies before, hopefully, a home fixture on the weekend prior to the Premier League campaign kicking-off.
The first of those away matches, will see Chris Wilder take his side to the Pirelli Stadium to face Burton Albion on Tuesday 16th July (KO 7.45pm), before a visit to Northampton Town four days later on Saturday 20th July (KO 3pm).
John Sheridan's Chesterfield will provide the next test at the Proact Stadium on Tuesday 23rd July (KO 7.30pm), prior to a game at newly-promoted Barnsley on Saturday 27th July (KO 12pm).
A potential home friendly in early August will be announced when confirmed, as will ticket information for all fixtures.
