For reasons not quite clear, Ole Gunnar Solskjaer was forced to wear a bib over his jacket on the Manchester United bench and it prompted a lot of folks to make the very same joke.
The 46-year old Norwegian was seen in conversation with the fourth official on the touchline and when the camera next panned to Solskjaer, he was sporting a yellow UEFA bib.
The most logical explanation would appear to be that the referee thought his coat clashed with PSG's colours and so the bib was put on to resolve the issue.
However, many people on Twitter joked that it was just part of a secret plan OGS had whereby he'd assume his super sub role once again.
Being honest, Solskjaer probably wouldn't have done any worse than Eric Bailly, who had an absolute stinker in the first half and was replaced by Diogo Dalot.
You might remember that Solskjaer has been involved in a fair amount of memorable United comebacks as a player so just maybe he has a trick up his sleeve...
United made a dream start at the Parc des Princes when Romelu Lukaku opened the scoring with the club's second-fastest Champions League goal and made it 2-1 on aggregate.
PSG levelled on the night just ten minutes later through Juan Bernat but United were back in the lead on the half hour mark when Lukaku pounced on a huge error from Buffon to put United ahead again with his sixth goal in three games.
