With the first-team currently continuing their pre-season preparations in Portugal, some of United's development squad departed for Malta on Tuesday.
The Blades will face Santa Lucia on Monday, as part of a week-long stay on the Mediterranean island, in addition to numerous sessions of warm weather training.
United's youngsters played two friendlies on home soil prior to departing, winning 1-0 at Tadcaster Albion, before going down 3-2 to Maltby Main on Monday evening.
Academy manager Travis Binnion remarked: "Pre-season isn't all about results, although it's always nice to win any game and importantly we've given a lot of the lads some good minutes already.
"Going away for a week to Malta will mean we spend a lot of time together as a group and it's always beneficial to take the squad out of their comfort zone, so they can really get to know each other."
