Thing you have to bare in mind is, this is the first season where 3 identical and potentially career ending injuries have occured where 2 of those injuries are within 2 months of each other, and the injury which potentially ended vaughan's career a couple years ago, and he is now suffering for it (he was before came back again). Hindsight is a wonderful thing for us fans, but i do think Moyse surely needs to look at this and do some sort of investigation about why this has occured twice in a relatively short period of time.
I dont want this to become so common we end up loosing all of our best players..that is why I am very concerned. ACL is potentially career ending, and there is no guarantee the same injury (as been explained above so well) will not plight the same players over and over, the evidence is right there in vaughan..this is why this type of injury needs special consideration and taken very seriously..its no good just coming out with "its just bad luck" we need to be sure those training methods which reduce these types of injuries are being taken on board seriously (and i cite arteta and jags as case in point..i honestly do not believe jags would have been injured like this had the training been compulsory for all first team players, it would be been reduced significantly, to the point it very likely wouldnt have happened..but now its happened twice so close together)..arteta and jags will likely suffer for the rest of their careers with these horrific injuries reoccuring.
