La Dea were 2-0 up and in control at half time but the substitution of Merih Demiral at half time through injury proved key. Rashford, Harry Maguire, and Cristiano Ronaldo all scored in the second half to put United top of the group.

Player of the match – Marcus Rashford
Marcus Rashford was the most dangerous United attacker in a lacklustre first half. He missed a couple of presentable chances, but then scored the goal that set United on their way to victory. He was taken off with a minor-looking injury in the 66th minute but was still a standout performer.
