In the meantime, Manchester United became the first team in UCL history to progress to the next round having lost by two or more goals at home in the first leg of a knockout match, while Thomas Tuchel's side rued missed chances yet again.
It was another heartbreaking night for the Les Parisiens, reminiscent of their defeat to Barcelona in 2017, when the Catalan giants became the first team to overturn a first-leg 4-0 deficit.
