Barcelona completed the unlikeliest comeback in UEFA Champions League history by beating Paris Saint-Germain 6-1 in March 2017. The Catalans lost in Paris, 4-0, and looked doomed. They looked even more doomed when Edinson Cavani scored an away goal at Camp Nou in the second half. And they were definitely done when, with 3 minutes left in normal time, they still needed three goals.
And yet, somehow, Barcelona did it.
Luis Enrique’s Barcelona is probably a higher quality than the version we have today, but let’s not forget that Arda Turan and André Gomes were on the pitch when Sergi Roberto (who had come on for Rafinha) scored the last-gasp winner.
