As NBA great Allen Iverson once infamously said: "Pracitce? We're talking about practice, man."
While the former basketball star's apparent indifference towards training was arguably taken out of context, his point was clear: there are more important things in life than practice.
Try telling that to the tens of thousands of Boca Junior fans who packed out La Bombonera stadium on Thursday just to watch their team practice ahead of the Copa Libertadores final, second leg.
Boca face fierce rivals River Plate at River's El Monumental stadium on Saturday with the tie locked at 2-2. It is the first time Argentina's biggest clubs have faced each other in the final of South America's equivalent to the Champions League.
The winner will not only be able to call themselves the champions of South America, but will book their place in the Fifa Club World Cup next month, taking place in the UAE for the second successive year.
