Manchester United have to negotiate an extra hurdle in their bid for Europa League glory following the end of the group stage matches. The Reds travelled to Real Sociedad last Thursday knowing that a two-goal victory margin over their La Liga opposition would see them finish top of the group.
Anything less would see them having to go through a two-legged playoff round in order to qualify for the knockout stage proper - and unfortunately for United they were only able to gain a 1-0 win, thanks to Alejandro Garnacho's first-half strike.
Ahead of the Europa League draw on Monday, MEN Sport has taken a look at how the playoffs work and who the Reds could be playing next.
