Barcelona's historic comeback disguises lasting flaws

There is nothing that can explain the last 10 minutes of Barcelona's stunning comeback against Paris Saint-Germain. Needing three goals to advance, Barcelona somehow conjured a gorgeous free kick from Neymar, a (questionable at best) penalty on Suarez and unlikely set piece goal from Sergi Roberto to move through. It was an incredible comeback, but one which doesn't provide much insight into Barcelona beyond sheer awe.
