Gregg Berhalter's January roster, which is entirely MLS-based players, will take on Slovenia in an international friendly on January 20. However, it will then be followed by the semifinal match in March against Jamaica. It will be make-or-break in the coming months for the striking core on the cusp of the starting XI, while those returning from injury and looking to make the roster will have to adapt fast if they want to impress the USMNT boss.
