Medical and sports science staff at elite clubs constantly review things like training load, injuries, reasons for injuries on an ongoing basis. There is unlikely to be any need for an urgent investigation, almost certain they do it as a matter of course anyway.

There was a good arsenal vision podcast with Darren Burgess who noted that Saka's and havertz's hamstring ruptures occured at the tendon, and more research needs to be done around how to strength the tendon as opposed to the muscle itself 🤷
It does seem to be a bit like monitoring an earthquake zone, in that you know they are likely to suffer these kind of injuries , but at present it is nearly impossible to predict when they might happen and how bad they will be!
