The Blades secured an impressive victory over La Liga's Malaga CF to conclude the six days of pre-season training in Spain.
At the Estadio Jose Burgos Quintana in Coin, an estimated 750 Unitedites were in attendance to see John Fleck strike the winner in the first half.
The Blades created the first chance on 12 minutes following a breakaway. Coutts, Fleck and Clarke were all involved before Sharp curled wide. Malaga hit back with a couple of chances in quick succession. Pablo hammered wide, Chori burst through but his shot was deflected and from the resulting corner Moore saved Borja's powerful header.
United grabbed the lead on 25 minutes. A number of players looked comfortable in possession and after a Carruthers pass, the Malaga defence backed off FLECK, who curled his shot beyond Roberto's right hand from a central position.
Fleck then beat two defenders on the left and provided an inviting cross but Sharp sidefooted wide and the skipper had another good chance on 37 minutes but Roberto was down quickly to make a save.
Boss Chris Wilder made four changes at the break and there were very few chances in the early part of the second half. Recio curled a free-kick over the crossbar and a run from Jony put the Blades under pressure but O'Connell sniffed out the danger.
Wright and Evans were introduced for their first action of pre-season, whilst Brooks let fly from 30 yards but substitute goalkeeper Andres Priesto saved. A looping O'Connell header from a Coutts corner was off target soon after.
Malaga finished the stronger. En Nesyri was in the clear but was called offside, whilst the Spanish outfit's best opportunity arrived on 87 minutes. Brooks was robbed by Adrian and after a lay-off, Moore saved with his feet as En Nesyri again looked for an equaliser.
Injury-time saw Malaga force two corners but United repelled them both to record a deserved victory.
