Omar Gonzalez has been challenged by USA boss Jurgen Klinsmann to take the next step in his career.

The 24-year old centre-back was a key part of the Galaxy's second MLS Cup in a row after returning from injury last season and Klinsmann wants him to now step up to international level after making just two senior appearances for the US since 2010.

"He needs to show us he's ready for a big step into international football," Klinsmann told Fox Soccer's Goals on Sunday show.

"He needs to show us that he wants to break in. He needs to show us that he's ready to guide a back line, that he's ready to communicate a lot and take over the responsibility.

"If it wasn't for his injury at the beginning of last year, he would have been with us already on a regular basis. Yes, obviously tremendous physical abilities. He grew under Bruce Arena into a very good, solid center-back but national team is another level. And so we are happy to have him now finally with us in camp and to see him work on a daily basis."
