I doubt he would go in jail. It would be hard to prove his intent to injure him
But his career is over, atleast in Spain or big leagues. It would be very difficult for him to recover from this experience. Fans won't let him have peace as well
It is legally tricky.
Because as a player when you step on the pitch, you already legally accepted the risks of injury.
But as a Gk, he way out of box. The way he tackled shows he was committed to foul him and not going for the ball at all.
So you could push him to jail.
There's case of medical negligence as well.
The Medical team took their time carrying him on stretcher and only give him CPR when he's on ambulance.
Very different approach compared to how Eriksen or Aguero case was handled.
Naturally, lower league divisions are under-invested
