Manchester United eased to a 2-1 win over Sampdoria on Wednesday in their pre-season friendly at the Aviva Stadium in Dublin, Ireland.
Henrikh Mkhitaryan scored after just nine minutes as United dominated the first half, but Dennis Praet equalised in the 63rd minute.
Substitute Juan Mata netted the decisive strike with nine minutes of normal time remaining in United's final match before taking on Real Madrid in the UEFA Super Cup on August 8.
The Red Devils almost made a disastrous start to the match when David De Gea gave away an indirect free-kick six yards out after scrambling to keep out a dreadful backpass from Daley Blind.
