The success of PSG at Manchester United (3-1) is extremely important.
Because it is historic: it is the second time in two years that the Parisians have won at Old Trafford by two goals.
And because it places Thomas Tuchel's men on the royal road to the knockout stages of the Champions League when they were badly embarked with three points acquired on the first three days of the group stage.
But a success against Leipzig (1-0) at the Parc des Princes last week and this victory in Manchester changed everything in this group H. Here are three teams with 9 points one day from the end of the group stage.
The possibilities of qualification are numerous, more numerous than those of elimination.
Manchester United-PSG (1-3): the ratings of Parisian players
PSG will receive Basaksehir Istanbul in its den next Tuesday in a very comfortable situation: a victory or a draw will send the capital club to the final phase of the Champions League.
And whatever happens in the other game between Leipzig and Manchester United, Germany.
At 11 against 10, Paris did not tremble and the Neymar-Mbappé team, even half charred, offered PSG the goal which promises them first place except for an accident against Basaksehir.
Even in the event of a defeat against the Turks, Paris would not necessarily be eliminated.
The only case in which he would miss the round of 16 would be a home setback associated with a draw in the match between the Germans and the English.
