Gabriel Martinelli and David Luiz were among the first Arsenal stars back in training at their Colney base on Monday.
Mikel Arteta's men had a pitch to themselves at the ten-pitch Hertfordshire complex in Colney.
The return to work is voluntary and players had to travel alone with only five allowed to train at one time.
A staggered series of one-hour sessions is spread throughout the day with medical and fitness staff overseeing each one from afar and the players banned from socialising with each other.
They even had their own specifically assigned football to avoid cross-contamination.
