Former U.S. men's national team manager Jurgen Klinsmann has said the brand new Concacaf Nations League is a "waste of time" for top-tier nations like the USA, Mexico and Costa Rica.
The inaugural Concacaf Nations League kicked off earlier this month, as every country in the region takes part in a competition designed to replace most international friendlies.
Though the competition is likely to benefit some of the smaller teams in Concacaf by providing more consistent meaningful games, Klinsmann is concerned that it will damage the region's top teams.

"I think the biggest challenge for the United States, or even Mexico or Costa Rica, for the key countries in this region, is you don't really have the highest competition outside," Klinsmann told ESPN.
