Mexico’s absence from South American competitions has stretched nearly a decade. The last time Liga MX clubs participated in the Copa Libertadores was in 2016, when Pumas, Toluca, and Puebla represented the country. Chivas and San Luis were the last Mexican sides to play in the Copa Sudamericana, back in 2008.
Since then, Liga MX and MLS have joined forces in regional tournaments under CONCACAF's umbrella, competing in events such as the Champions Cup and the Leagues Cup - a move that, while financially successful, has also limited Mexican clubs’ exposure to South America’s highest level of competition.
