It's supposed by various sources that the 32-year-old has begun his recovery phase after an injury he got on Monday. He is reported to have started individual training managed by team physiotherapists.
Just to remind, the Argentinian has been out of action since Monday due to a right calf injury he got during his first training session this summer. Leo didn't travel with the entire squad to the United States and revealed via his official media accounts that he would be "out for a while".
However, with the incoming news, the possibility of Messi's preparedness for the first official game of the season has increased.
