Former Red Devil Di Maria wasn't exactly given the warmest reception upon his return to Old Trafford, given his thoroughly underwhelming spell at the club during the 2014/15 season. But he appeared to swear in English during the goal celebrations in a video captured by BT Sport.
Di Maria cost a British record £59.7million when he joined United from Real Madrid in August 2014 but left within a year, having scored only four goals in 32 games as Van Gaal's tactics prevented him from playing in his natural position as a winger. These are things that happen and people took it badly. There were problems with the coach at the time.
Before kick-off, a number of PSG supporters set off flares in the away section at Old Trafford.
In addition, Man United captain on the night Ashley Young also "pushed" Di Maria into the hoardings in the first stanza, with fans enjoying every bit of the action.
"Referee Daniele Orsato got it right - Young's challenge on Di Maria did not warrant a second yellow card", Clattenburg wrote in the Daily Mail.
'I'm happy that he stayed confident.
But late in the first half, Di Maria's end was up. "If you tease him, it does not make him weaker", said his manager Thomas Tuchel, summing up his contribution perfectly, even noting Di Maria's weak start to the game as he won just one of his nine duels.
Paris Saint-Germain's head coach Thomas Tuchel said of the shove: "There was no need to push Di Maria into the fans but I don't think it was on goal".
