Soccer America Senior Editor Scott French is in Argentina, where talent scouts are everywhere one turns, seeking young stars for clubs all over the world. Here are three Americans who have impressed: 1. Oguchi Onyewu (Clemson). Incredible physical specimen with unlimited potential, right back has everyone drooling — and he hasn’t yet had opportunity to showcase his attacking skills. 2. D.J. Countess (UCLA). The last-minute error against Ukraine aside, netminder has been sensational, arguably the MVP of Group C. The total package. 3. DaMarcus Beasley (Chicago Fire). Speedy winger-forward’s every run greeted with hushed anticipation from the Mendoza crowd, especially during two-goal, one-assist performance vs. Chile. The group’s most exciting star, scouts agree, has a bright future in Europe if he wants it.
