Barca did the unthinkable last night by overturning a 4:0 deficit, to progress to the last 8 of the champions league by trashing psg 6:1. It was a neymar inspired barca side who won the two legged tie 6:5 on aggregate score. So what are the lessons you learnt from this unforgetable night in barcelona?

I think I learnt two lesson from it.
1. Criticism don't hurt, it only inspires you to work hard. Because barca was criticised even by football greats like arrigo sacchi and raymond dommenech, but they alwways believed that they ccould do it.
2. Neva in your life underrate anybody, they might turn out to surprise you. Because psg thought it was done and dusted, but barca turned it around and surprise them.
