Cynics should not be fooled into thinking that this result came against an under-strength foe.
Santos only has Neymar and are no better than 10th in the world. 
In recent years, teams from South America have had their talent stripped away by big-spending European sides, and the exodus of talent has been extraordinary.
Santos could just afford to keep Neymar, can't carry a billion in debt like Euro clubs. 
No, Barcelona’s victory was not a simple matter of finances but rather the implementation of a system that might be impossible to properly combat.
Just answered this. 
Europe’s best teams have tried and failed, and Santos was the latest to be sliced open by Barca’s passing game, which resembles death by a thousand cuts.
How about having a Euro football team (equipment) play the Superbowl champ and write about that.
