Arena is just more of the same. The US needs to try someone new since clearly what they have been doing so far has not been working. The rest of the world is just laughing at US soccer and it shouldn't be that way, there's so much talent here.
I see where you're coming from but Arena is going to put pressure on the US to produce better forwards. He knows the international soccer landscape and can identify exactly why we suck.
Arena knows what he's doing, he's been involved in international soccer for a while. Klinsmann was a bad choice despite his track record and Arena will be tasked with undoing a lot of what Klinsmann did. I think he deserves a fair shot.
