The UEFA Champions League clash at Old Trafford ended 3-1 to the visitors, but the teams went into the break level at 1-1 after Neymar and Marcus Rashford both scored in the first half.
After the interval, United dominated the play and missed several big chances. Against the run of play, Marquinhos put PSG in front before Neymar once again got on the scoresheet in injury time, just when the Reds had been going all out for another equaliser.
Maguire was understandably dismayed when he faced the media after the match.
“It's a disappointing night,”
our defender told BT Sport.
