RUMOURS: Barcelona testing players' DNA to prevent injuries

Barcelona have been testing the DNA and saliva of their players, including Lionel Messi, Luis Suarez and Neymar, in order to stave off possible future injuries, according to the Daily Mail.

The information gathered from these tests supposedly allows the medical and fitness team to determine which players are more likely to suffer injury, therefore enabling staff members to tailor specific exercises for each individual.
Despite having already played 42 games this season Barca - four more than upcoming Champions League opponents Arsenal - the squad are currently without just one key player, Brazilian midfielder Rafinha.
