Can was given an extended break as he was part of the Germany side that reached the Euro 2016 semi-finals.
The 22-year-old midfielder travelled to his parents home town in Afyon, Turkey before heading out to California.
Can has been busy partying in LA and Las Vegas along with Arsenal star Mesut Ozil but he will have to get back into the swing of things as the Reds will take on Premier League rivals Chelsea at the Rose Bowl on July 27.
Liverpool legend Steven Gerrard will be in attendance alongside his LA Galaxy team-mate and ex Chelsea full-back Ashley Cole.
