Diego Luna, Jack McGlynn, two defenders and more to watch this summer as the USMNT look to have an impressive summer on multiple fronts.

The number four was not kind to the United States men's national team on Tuesday night at Nashville's Geodis Park. The short-handed Americans gave up four goals in the first half to Switzerland and were handed their fourth straight loss in the process.

Tuesday's 4-0 capitulation against Switzerland will no doubt leave USMNT boss Mauricio Pochettino wondering what he's got himself into.
