Juergen Klinsmann insists those players who seem on the fringes of the USA national team are never too far from the thoughts of the coaching staff.

The German tactician provided a video for the press ahead of Wednesday's friendly with Mexico in San Antonio stating that those players not selected for the current squad are not necessarily out of reckoning for future national team involvement.

"It's very important that the players understand, even if they are for a long stretch of time not with us, they're always observed," Klinsmann said.

"We always watch them.

"We kind of suffer with them when things are not going so well, like Julian Green, like Juan Agudelo when he had his journey through Europe, or Brek Shea over that time, or Joe Corona was injured.

"So every one of them has their own individual issues, and they have their down periods, and they have their struggles, but that doesn't mean they are out of sight. We watch them.

"We are communicating with them and we want to help them. And when they're kind of coming back up and there is an opportunity like now, other players are not there."
