'They didn't let me have my best time there,' said Angel Di Maria in a recent interview about his time at Old Trafford.
Di Maria is considered a flop in the eyes of United fans. The winger signed for £59.7million from Real Madrid in 2014 and largely did nothing during his one year at United before he moved to Paris Saint-Germain.
So, Tuesday night was his chance to make a statement. After all, he had barely been mentioned in the build-up.

The talk had centred on how PSG would do without Neymar or Edinson Cavani. Kylian Mbappe entered the conversation due to being fit yet no airtime for Di Maria.
It was only when he was booed walking into the ground that he became a topic of interest for Gary Lineker, Rio Ferdinand, Owen Hargreaves and Paul Ince in the BT Sport studio.
It was a mistake. The 30-year-old had scored in his last two Ligue 1 games and understands PSG's philosophy of fast, attacking football.
His boss, Thomas Tuchel, had alluded to it in his pre-match press conference.

'Obviously we're going to be missing a couple of key attackers, but you don't change your identity for that reason,' Tuchel said.
Di Maria was positioned on the left with the expectation of his manager to get forward in a flash and be able to support Mbappe, who was playing in front of Julian Draxler.
He kept making run after run after run but the passes forward weren't finding him. Each one sloppy, under-hit or not to his feet.
In the end, he did the work himself when the ball became loose just inside the left touchline.
He chased after it, took a touch and then took a hit from United captain Ashley Young, which sent him into the pitchside barriers.
It is a steep drop from the pitch to the advertising boards at Old Trafford and Di Maria felt the full force of Young's rash and out-of-control challenge.
Maybe it was at that point, after being sent to the ground and receiving insults from the home supporters, that he felt enough was enough.
