Arsenal forward Alexis Sanchez is upping the intensity of his training routine in a bid to get back to full fitness.
The Chilean, who has been sidelined with an abdominal muscle problem, posted a photo during a heavy workout, showing him to be out of breath and sweating.
Sanchez missed Arsenal's opening-day thriller against Leicester last week, where the Gunners wrestled the game back to win 4-3 at the Emirates.
And the Gunners will again be without their talisman when they make the trip to Stoke on Saturday evening.
