The future of Jurgen Klinsmann as manager of the United States remains very uncertain following their losses to Mexico and Costa Rica.

The U.S. Soccer Federation has been gauging the interest of potential replacements since at least late last year.

U.S Soccer has been in touch with both Bruce Arena and Peter Vermes within the past 12 months.

Arena's contract with the Galaxy was set to expire next month, but the 65-year-old recently signed a two-year extension with the MLS club. The new deal would allow Arena to freely leave if offered the national team job.

Tab Ramos, Klinsmann's current assistant, could also be a candidate for the position if the manager is let go.

Klinsmann is under contract through 2018.
