When it comes to the hiring of a premier international manager, it's usually a case of "Show me the money." Hiring top talent requires paying top dollar, and as it pertains to the next coach of the U.S. men's national team, the U.S. Soccer Federation seems willing to oblige, both in terms of the amount and the mechanisms by which said manager is compensated.
For the entirety of the USSF's existence, the compensation paid to the USMNT manager came strictly out of the federation's coffers. That amount has ebbed and flowed to a degree, but mostly increased over time.
