With ten senior players ruled out injured and Kylian Mbappe in the hottest form, Manchester United were dealt a huge 'mountain to climb' as they headed to Paris two goals down in the UEFA Champions League round of 16 second leg.
With Paul Pogba suspended, Fred and Scott McTominay were the reinforcements, similarly to when Pogba was injured last year.
Lukaku got United off to a flyer
Whether United fans were pleased or disappointed to see Romelu Lukaku depart last summer for Inter Milan, there is no doubt he played a pivotal role on that historic night.
In the second minute, Lukaku pounced on a loose ball, knocked it past Gianluigi Buffon and squeezed in a tidy finish from a tight angle to put United one goal up on the night.
The French side did not take long to react as Juan Bernat equalised just ten minutes later, which he and many thought would kill off any United hopes.
Buffon - the ten time Serie A winner and World Cup champion - then handed United a second as he spilled Marcus Rashford's long distance strike into the path of Lukaku for an easy tap-in. With the score 3-2 to PSG on aggregate at half-time, United were one goal away from victory on the away goal ruling.
Patience and nerves were tested
In the 55th minute, the former United man, Angel Di Maria, thought he had upset United fans one more time. His chipped effort beat David de Gea but was ruled offside.
Mbappe got round De Gea in the 84th minute but Chris Smalling kept his side in the game as he made a last-ditch tackle which led to Bernat hitting the outside of the post.
Then came the 90th minute when Diogo Dalot found space in the middle of the park and let one rip, it took a deflection and originally diverted away from goal for a corner kick.
Presnel Kimpembe may have scored in the first leg, however, that is long forgotten as it was ruled that his elbow got in the way of Dalot's strike to deflect it away from goal. Whether it was intentional or not, VAR intervened and we saw the first handball decision that we are so used to seeing now in football.
Then came the penalty...
Oh and he's smashed it in!
Were the words from Darren Fletcher - the BT Sport commentator - as Rashford hammered home the winner in injury time.
United had overturned a two-goal deficit away from home - something which had never been achieved before.
The birth of Mason Greenwood
It was not only a night to remember because of the result but Ole Gunnar Solskjaer handed a professional debut to Mason Greenwood. The 19-year-old has now made 57 appearances for the first team scoring 18 goals.
