After landing in California on Thursday afternoon, Unai Emery's side took part in their first training session in Los Angeles on Friday morning.
In the first of their two sessions, the likes of Mesut Ozil, Pierre-Emerick Aubameyang and Alexandre Lacazette were put through some light activation work, passing drills and high-intensity sprints.
Our club photographers were also at our training base and sent back these pictures:
