Not a clue how you've interpreted my post that way.
Firstly, it's a given that a ton of footballers injuries CAN be attributed to their mentality. My point was that given Ney's mentality/attitude has been all over the place, it's not a surprise he's more injured now. Many sport psychologists/physios have already explained the link between mental state and physical state so I'm not going to dive into it.
No, Messi didn't prevent Neymar getting injured, but Messi helped keep him in check mentally which allowed him to stay in better mental/physical shape.
Again his 2 big injuries were metatarsal broken bones. You're really tripping here. If it was muscular injuries *cough* Dembele *cough* ... you might have a point.
