3 changes the USMNT can expect under Bruce Arena

Former LA Galaxy head coach Bruce Arena has been named manager of the U.S. men's national team once again, returning to the role he left in 2006 after Jurgen Klinsmann was fired from the post Monday.

Here are three changes fans of the Stars and Stripes can expect to see in Arena's second spell:

A more varied player pool

Klinsmann's preference for German-American players is well-documented, as is his preference for international-quality players to play in Europe instead of in Major League Soccer. That may have correlated to the late call-ups offered to MLS regulars like Sacha Kljestan and Darlington Nagbe, as well as the cold shoulder to players like Benny Feilhaber or Justin Morrow.

Arena's criticized Klinsmann for selecting too many foreign-born U.S. internationals, telling ESPN FC's Doug McIntyre in 2013: "Players on the national team should be - and this is my own feeling - they should be Americans. If they're all born in other countries, I don't think we can say we are making progress."

That's ... not great news for the likes of John Brooks, Jermaine Jones, Christian Pulisic, or Julian Green, but there's no indication they will be dropped entirely from the team, either.

In any case, Arena will likely afford more opportunities to players plying their trade in MLS, having seen firsthand the quality they possess. Regulars like Kyle Beckerman, Mix Diskerud, Michael Orozco, and Timmy Chandler will have to fight for their spots once again, too.

Consistency and a clear system

All this talk of a 3-5-2 formation in recent weeks is just one of multiple unnecessary changes Klinsmann made to the U.S. system. Under Arena, the team will likely find one way of playing and stick to it, even if it is a return to the days of long ball played to a pair of strikers up top.

Long gone are the days of Taylor Twellman and Brian Ching up top, Landon Donovan as a No. 10, or Pablo Mastroeni in defensive midfield. Arena will have an entirely new crop of players to work with and needs to adjust his tactics and system accordingly.

It's not yet clear how Arena intends to line up his squad; he could mirror the LA Galaxy's 4-2-3-1, or try something new and unconventional. The latter is a risk he can only take if he can get the team to qualify for the 2018 World Cup, which brings us to the third point.

A return to results-first thinking

Klinsmann wasn't just the head coach of the USMNT - he was also the technical director, in charge of youth development initiatives, and overseer of many different levels and branches of the organization and its structure. His was very much a long-term vision, born out of a need for reform.

Arena enjoyed a trophy-laden career with the LA Galaxy, winning the MLS Cup three times as well as the MLS Supporters' Shield on a pair of occasions. He returns to the USMNT having posted a 71-30-29 record in his last tenure, or a 54.6 winning percentage.

At 65 years old, Arena will likely focus primarily on the upcoming World Cup, and his immediate goal will be successfully getting the U.S. out of the Hex stage of CONCACAF qualifiers. He is under contract through the 2018 cycle and will not need to concentrate on making any sweeping changes.
