If you're squeamish, don't watch this, or read on any further.
I wasn't watching this match and I'm just catching up on highlights plus replays and such now, so I can only imagine the suspense: his face is towards the camera, and it's obvious that he's quite literally dead-- completely lifeless, haunting eyes. At that moment, it's like watching a ghost: he's gone. The ironic thing for him is that what saved his life was that the inevitable happened on a football pitch, with trained equipped medics seconds away, versus later on in bed that night like with Davide Astori.
He's a player who has struggled to replicate the form of his earlier years, and maybe now we know why: he probably developed a heart condition a few years ago and wasn't aware of it. Of course, he'll never play football again ala Fabrice Muamba-- but the important thing is that he's alive, plus he's such a talented guy he has a million other things towards which he can excel. And now that he knows about his heart and can get the proper treatment or surgery, he could live to be ninety years old.
Besides that, the twenty-nine year old started senior football as a teenager: that's an over decade-long professional career, playing at the highest levels. In other sports, that would be considered a super long time from where one could build an entire "hall of fame" resume-- so he shouldn't have any regrets: it's as if he had a catastrophic knee injury or something, and the doctors say he shouldn't run on it anymore. I'm sure he'll be amazing at whatever he decides to do in life next: apparently he's very upbeat in the hospital, and doing very well.
