Same deal, I'm 31, and drinking to excess now messes me up for a good week, especially tracked by my workout progressions. It's why @Zacheryah doesn't drink at all. He's a competitive powerlifter, and the less alcohol one drinks, the better one recovers between workouts and makes gains. It's the same deal with elite athletes of every sort. And Vidal's game is 90% based on his insane drive, crazy physicality and athletic ability... The latter two are adversely affected by drinking booze regularly.
Anyways. It will be interesting to see how his career goes over the next couple years, and whether he can reign in this behaviour and be a star player into his 30s, or if he continues the sharp decline he currently appears to be on. I certainly don't wish ill upon him, but at this point I'm kind of indifferent to him. Couldn't really care either way. I'm grateful for his Juventus time and what he gave us, and the rest of his career isn't even a minor footnote for me.
