USA coach Jurgen Klinsmann is keen to help rebuild the confidence of FC Dallas midfielder Brek Shea.

Shea earned a surprise call-up for the USA's friendly with Mexico.

"I've had good conversations over the last few weeks with Schellas Hyndman, and we both see a lot of upside in Brek Shea," Klinsmann said Sunday. "We all knew that after the big disappointment for not qualifying for the Olympics, that our youngsters … they would eventually fall into a hole. They would go through emotional roller coasters. And this is what happened with Brek.

"He needs our support and the feeling that we're also there when things are getting tough.

"And things got tough for him. This whole generation that should have been in London the last two weeks, that was a tough pill to swallow for them. And now we're at a point where we say we have to integrate those players into our plans, and give them playing time and possibilities to be close to the international level and the senior national team."
