The Sun reports that Lukaku was "disappointed that Pogba took the penalty as he was on a hat-trick at the time" and that it "sparked a dressing-room row".
Slovenian referee Damir Skomina awarded a spot-kick after reviewing the images when he had been alerted of a possible handball by PSG defender Presnel Kimpembe in the box.
"Instead of picking out the negatives and trying to find what Pogba can't do, find the positives and realise that he is the most effective midfielder in the Premier League when he is played in his proper position and utilised in the right way".
But United, to their credit, recovered and went ahead again just after the half-hour mark as that man Lukaku bagged his third brace in as many games, tapping home after Buffon fumbled a long-range Marcus Rashford effort. "There is one newspaper that everybody reads that they're like.I can say, "You are all racists", you all know who you are".
PSG, though, have lost just three games all season, and are now on a run of eight successive victories in all competitions.
And United fans are convinced Lukaku did it intentionally.
"If you look at the games we played, everybody was talking after the first four games because we played against less opposition".
"It's the first time he travels with us - he didn't expect to come, but that's part of being here".
Shaw loved celebrating with such United greats after a win that only highlights the positivity and belief instilled by 1999 treble hero Solskjaer.
"Mo Salah gave the penalty to Bobby (Firmino) and I nearly cried because we all know how much Mo wants to score goals", Reds boss Jurgen Klopp had said to BBC Sport after that game against the Gunners.
"I felt we were capable of pulling something off and even earlier today I said to Lee Grant that we were going to win, I could feel it".
