Regardless of how it ended, the 2014 FIFA World Cup was a great step for the United States Men's National Team. They played in an extremely tough group, and they did what they needed to get out of it. Now, they need to find a way to build on that success.

The most obvious stage for international success is the World Cup, but the USMNT has plenty of chances to prove themselves before 2018. The first opportunity of 2015 will provide an excellent test, as the team faces off against Chile.

According to Fox Sports, the team has been training relentlessly, and they have focused on improving the fitness levels and tactics of the players so that they can outwork opponents late in matches and execute at crucial points.

"You want to see the team stretch it as far as they can," Klinsmann said during a press conference before the Americans trained at Estadio El Teniente on Tuesday afternoon. "Obviously, they are not all the way there yet. We don't know yet how many minutes at highest level, the highest tempo is there. We want them to give everything they have."

Chile will not have some of their best players available for this match, but they still have a deep and talented squad that is more than capable of winning the match.

"We've seen them," Klinsmann said. "We've scouted them. We know those are all very ambitious players. They want to prove to Sampaoli that they belong in the first group. They want to impress the players that are right now in Europe. We expect a very aggressive, a very energetic Chilean team. We've prepared our team for that. Hopefully, we can hold our ground and go in the other direction as well."
