The Holland defender's half-clearance led to Paris St Germain's crucial opening goal to pave the way for the hosts' 2-1 victory and leave Jurgen Klopp's side facing a must-win encounter at home to Napoli if they are to progress to the knockout stage.
Juan Bernat and Neymar scored to put PSG in control in the first half in the French capital, but a James Milner penalty on the stroke of half-time ensured this pivotal game remained in the balance until the death.
Mohamed Salah fired wide before Marco Verratti was perhaps fortunate only to be booked for a high tackle on Joe Gomez.
What was more impressive however was they way they managed the game throughout the 90 minutes, as Jurgen Klopp's side rarely threatened Buffon's goal, to give Tuchel's side a priceless three points in Group C.
"The problem I have a little bit is that I, again, have to create the stories with my name - "Klopp said", "Klopp said", the Liverpool manager told BT Sport.
"The little hurdle was then the 500,000 interruptions in the second half".

"We will make the proper analyse [sic] and fly back and prepare for the derby and for a few more games".
Tuchel refused to be drawn on the matter, but said Klopp, like many coaches, may have been using the referee to keep the pressure off his team. "But now we need to look forward and the only option for us to qualify is to win against Napoli, no matter what".
Angel di Maria had forced a fine save from Alisson with a dipping volley before Paris went in front in the 13th minute.
Salah curling a shot wide was as good as it got for the visitors, for whom Gomez was having a tough time as having been nailed by a reckless over-the-top Verratti challenge was then booked after losing possession to and then pulling back Neymar.
Not everybody shone but the majority of PSG's star names lived up to their billing and produced some scintillating football at times - notably in the first half. Meanwhile, Sadio Mane is fit to start, after initially being a doubt due to illness. "We know how strong we are and we always knew we could do it", said Mbappe.More news: ‘Sanskari Stark’ Sophie Turner Wore Red Desi Attire For PC’s Puja
