Club America manager Miguel Herrera doesn't like the idea of new Mexico boss Tata Martino's "microcycles" but says the decision to allow players to go is out of his hands.
The first roster was announced Friday, with Martino set to work with 24 domestic-based players from Sunday night until Tuesday or Wednesday afternoon depending on when their clubs are in action. The former Argentina and Paraguay manager is looking to gain familiarity with a new group by bringing in players for a few days at a time early in the week before they return to their club teams.
