In a match dominated by the Reds, headed goals from Diogo Dalot and Marcus Rashford in each half were added to by a late Cristiano Ronaldo strike to settle the victory.
The result, our fourth win of the group stage, means there will be a showdown at Real Sociedad next week to decide who takes top spot and avoids having to play off against a third-placed side from the Champions League. United must win by two goals to topple the San Sebastian outfit on the head-to-head, after their 1-0 victory at Old Trafford.
FIRST HALF - LATE BREAKTHROUGH
Virtually from the moment United kicked off, the visitors sat into a robust defensive shape with all 11 players behind the ball, inviting the Reds to come at them.
