River Plate fans snapped up tickets for the second leg of the club's Copa Libertadores final against Boca Juniors in minutes today, ensuring the Superclásico clash will be watched by a capacity crowd.
After a 2-2 draw at La Bombonera last week, the arch-rivals go head-to-head at River's Monumental stadium on Saturday, November 24.
Illustrating the extent of demand for tickets, the website selling the tickets crashed almost immediately, but after it came back online, tickets sold out rapidly.
"Sale of remaining tickets, exhausted", the club tweeted.
Officials at the club estimate that income from sales could exceed 100 million pesos (approx. US$2.7 million). The Monumental, in Nuñez, can accommodate 67,000 spectators, though only River fans will be present for security reasons. The club has around 40,000 season-ticket holders, whose seats are guaranteed.
The remaining tickets cost between 1,200 to 3,200 pesos (between US£32-87).
