Ferran Torres had Barca ahead before PSG fought back through goals from youngster Senny Mayulu and Goncalo Ramos.
After the match, Enrique was delighted. But he lost his smile for a moment at the press conference to refocus a French journalist.
The latter had asked him: "Jules Koundé said that your victory was deserved and that he was surprised by the physical superiority. It's a bit surprising given that you had no preparation. Were you also surprised by the physical quality of the team?"
Lucho replied ironically in French: "No... No. If you say no, I'll say yes. And if you say yes, I'll say no. If we're the team in Europe that has trained the least... it's not true. How do you say that in French? A cliché is something that everyone repeats, but it's not true. It's not true. It's a cliché, that's all. It's a cliché that everyone repeats all the time.
"We have to remember that we suffered a lot during the league phase last season and that moment is important for confidence."
He then said the performance: "I have to say that we played a very good game. It was difficult at the beginning because they had the ball and, as always, Barcelona has a lot of quality players. The first 20 minutes were difficult.
"We scored, gained more confidence and came out with this draw at halftime. We were superior in the second half.
"Whatever the players, whatever the problems, we are there, as are the fans. It's an important victory because playing against Barcelona is always complicated."
