And so it is time to see what United States Men's National Team manager Jurgen Klinsmann is really about. Ever since assuming the role of both manager and technical director of the USMNT and US Soccer as a whole, Klinsmann has spoken quite a bit about what he wants he to do. 

He wants to reform the program in this country, develop the country into a real footballing nation. He wants to get this country to produce consistent top class footballers. Finally, and most importantly, he wants the USMNT to play attractive, attacking football which leads to results.

There have been both highs and lows. Winning the 2013 CONCACAF Gold Cup, getting out of the Group of Death at the 2014 FIFA World Cup and friendly victories on the road at Italy, the Netherlands and Germany have been some of the greatest triumphs in the history of American soccer. However, on the whole Klinsmann has failed to deliver what was promised.

The Gold Cup victory came in an off year, one in which nearly every country sent a B team and the Americans had the benefit of Landon Donovan in imperious form. The triumph over Ghana in the group stage in 2014 was due largely to a sterling defensive performance; after the Americans opened the scoring in the first minute they were comprehensively dominated for the next 80 until Ghana equalized. Tim Howard may have had one of the greatest ever goalkeeping performances against Belgium in the Round of 16 in Brazil, but the US were so outplayed in that match that had Howard not been playing the game of his life the Americans would have lost 3-0, maybe 4-0. Finally, those great friendly results came in friendlies; in the end, they don't really matter. 

The debate over whether or not Klinsmann should remain the boss of the USMNT has raged since the US crashed out of the Gold Cup semifinals against Jamaica this summer. The loss was unexpected, and some said that the only reason Klinsmann retained his job was because of the drama which surrounded Mexico at that point in time. Yet, it goes deeper than just that.

US Soccer is in quite deep with Klinsmann. He has attempted to overhaul the youth system in this country, and is so integral in the hierarchy of the soccer governing body that it was unlikely that loss would mean his end. Additionally, the Americans had the luxury of knowing that even if they didn't win the Gold Cup, they would have Saturday's one game CONCACAF Cup playoff to determine the region's representative at the 2017 Confederations Cup in Russia. That was the stated goal at the beginning of the year, and as long as that wass alive for the US, Klinsmann was never going to be under too much pressure. 

In other words, Saturday's match ought to be all or nothing.

Following the highs of the victories over Holland and Germany in June, the Americans have visibly regressed. The defense has disintegrated, they lacked any coherent identity in the Gold Cup and the shellacking doled out by Brazil left quite a bit to be desired. It is time for Klinsmann's moment of truth.

If the United States is victorious on Saturday night, the manager has earned the right to see out the World Cup Qualification cycle and to take them to Russia in both the summers of 2017 and 2018.

If they lose, then it is time for the Americans to move on. It's time for a new manager to be brought in, someone of the Caleb Porter mold, to see what they can do with this team, and whether or not they can continue to move them forward.

It's all up to the result on Saturday night now.
