Arsenal's pre-season preparations have gone up a gear this week.
Training is becoming more intense with a double session scheduled for Tuesday, and the players completed the first of those in the morning.
Arsène Wenger and his coaches oversaw a tough workout in stifling humidity before the squad returned to their hotel to rest.
Tuesday evening will see an open training session take place at the My Dinh National Stadium in Hanoi - with thousands of fans expected to attend.
Here's our picture gallery from the morning workout.
