I see discussions here about permanently signing him, some obligations and conditions are mentioned. What is the need of this? We must and we will sign him, regardless of the injury.
We all hope he will be back same as before/better. Personally, I think he will be fine. He is young, determined, pasionate... Even if he comes back at 90% he will be great player to have. I just hope he wont be rushed back and we take all the time he needs to have him back on the field.
