If it is the ACL something is seriously wrong with that Olimpico pitch. How many players have had the exact same injury played there now? It can't be just a coincidence
it isn't. there was an article on the subject after demiral and zaniolo ruptured their acl's during the same match. the number of acl injuries on that pitch is simply out of the ordinary
Neither of Landucci or Allegri have any form of medical training. It's up to the physios and the player himself to know when to come off after an injury.
