Anthony Martial scored from the spot in first-half proved decisive as Manchester United beat Partizan Belgrade 1-0 in the Europa League encounter on Thursday night.
Red Devils won an away game for the first time in 12 games -since their glorious European night at PSG in the Champions League.
The French striker who is making his first start since August, sent Vladimir Stojkovic the wrong way from the spot after 19-year-old defender Brandon Williams won the spot-kick.
Williams' burst forward to draw a foul from Nemanja Miletic was one of the few bright spots in an otherwise uninspiring United display.
And it helped ensure that Ole Gunnar Solskjaer's team won for the first time in 11 attempts away from home with their only shot on target as Manchester United moved top of their Europa League Group L with a victory a step closer to the knockout stages though, and at least breaks Solskjaer's winless run on the road.
