Puebla, Toluca and Pumas all could struggle to reach the heights Liga MX side Tigres did in the 2015 Copa Libertadores, writes Jon Arnold.
Last year was generally a success for Mexican clubs in the Copa Libertadores, South America's version of the Champions League. While Morelia was bounced in the first stage and Atlas finished last in its group, Tigres fell just short of becoming the first Mexican team to win the competition.
Tigres' defeat to River Plate in the final served to show that Liga MX's elite teams are on par with the top teams in Argentina, Brazil and the rest of the continent.
