Klinsmann was satisfied with their 1-1 draw against Mexico for his first game in charge.
Shea was impressive and he told Sporting News: "He definitely brings positive energy. He's all about, 'If you mess up, no big deal. Just go and do it on the next play.' I really like that about him.
"When he said that, you don't really hear that much To have the freedom to do what you like and not really have a set, 'You have to do this or this,' It just gives a player that much more confidence."
