Thomas Tuchel is not the only highly paid, big-name coach struggling to make an impact at international level at the moment.
Mauricio Pochettino watched his USA side go 4-0 down inside 36 minutes of their game against Switzerland in Nashville.
They have lost four games in a row for the first time since 2007 and the first time at home since 1988.
It is hardly the best backdrop for Pochettino to take a youthful squad into a CONCACAF Gold Cup campaign that starts against Trinidad and Tobago on Sunday.
