Anthony Martial’s first-half penalty proved decisive as Manchester United moved top of their Europa League group with victory at Partizan Belgrade.

Martial, making his first start since August, sent Vladimir Stojkovic the wrong way from the spot after United’s 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.
