Will be interesting to see how one of the fitter, healthier people in the world is affected by COVID. I'd imagine he will be completely asymptomatic.
He`ll most likely be fine and 99% won`t have any long term issues from it but being healthy and fit doesn`t automatically mean asymptomatic or very mild course of the disease, even for professional athletes. Genetics most likely play the biggest role.
Gündogan had it and he said it was quite heavy with him feeling like shit for days and that he doesn`t remember having an infect as bad ever before.
